An actor has done their job well if they can make the viewer believe that their character has excellent chemistry with their fellow actors. It can be even harder to truly portray that they are madly in love with another character. In reality, though, on-screen chemistry isn't always what it appears to be. Of course, the audience understands that performances are just that, but tension behind the scenes can be an unforeseen complication for any starring duo.

For some actors who don't get along, it's certainly a feat on both ends if they can pull through and finish their work on the film. Others, however, clashed so much that they either held a lifelong grudge or did everything in their power to stop working alongside their co-star.

10 Shannen Doherty And Jason Lee (Mallrats)

Shannen Doherty and Jason Lee in Mallrats

Kevin Smith's Mallrats starred Jason Lee in his mid-twenties, just before his career took off. Other Mallrats characters include his on-screen girlfriend, who was played by Charmed's Shannen Doherty. Mallrats, having been poorly received when it was released, has become a cult classic over time. Fans of the View Askewniverse can expect a sequel to be released sometime soon.

Though Brodie loses his girlfriend, Rene, at the beginning of Mallrats, they seem to complement each other as a couple. Unfortunately, the reality was entirely different as Jason Lee (Brodie) called Shannen Doherty (Rene) "rude, spoiled, and remarkably unpleasant."

9 Barbra Streisand And Walter Matthau (Hello, Dolly!)

Barbra Streisand and Walter Matthau in Hello Dolly

It's not unusual for arguments to happen behind the scenes but on a film that revolved around finding love and happiness, it's a little ironic. The 1969 musical Hello, Dolly! starred Barbra Streisand as the matchmaker Dolly Levi, determined to do her job well in Yonkers, New York.

Dolly manages to help Ambrose match with Horace Vandergelder's niece and ends up agreeing to marry Horace. Though their relationship on-screen seems rather forced, it was undoubtedly strained backstage with Walter Matthau carrying such an extreme hatred for Streisand. Matthau even said Streisand is "no more talent[ed] than a butterfly's fart."

8 Anthony Hopkins And Shirley MacLaine (A Change Of Seasons)

Shirley Maclaine and Anthony Hopkins in A Change of Seasons

The release of A Change Of Seasons in 1980 was a commercial and critical failure. A Change Of Seasons followed a married couple who were engaging in separate affairs at a ski resort. A Change Of Seasons is an awkward and uncomfortable story of infidelity and on-screen arguments between the two main characters, who were played by Anthony Hopkins and Shirley MacLaine.

Whether the off-screen issues arose from the complicated result of the film or from their lack of chemistry, Hopkins has mentioned that MacLaine was "the most obnoxious actress [he'd] ever worked with," and MacLaine has reciprocated the same feeling.

7 Marilyn Monroe And Laurence Olivier (The Prince And The Showgirl)

Unfortunately for Marilyn Monroe, this wouldn't be her only spat with a co-star off-screen. Still, her issues with Laurence Olivier were based on how she was treated by her producer and co-star on the set of The Prince And The Showgirl.

Olivier claimed to have many issues with Monroe's performance, including forgetting lines, showing up late, and having trouble with relating to her character. The complicated relationship between Marilyn Monroe and Laurence Olivier on this set is shown in-depth in the biopic My Week With Marilyn.

6 Nick Nolte And Julia Roberts (I Love Trouble)

Audiences might feel indifferent about how Julia Roberts and Nick Nolte got along behind the scenes of I Love Trouble. Still, the way their characters treated each other on-screen was far different from the actors' dispositions.

The couple held the same amount of romantic tension as viewers would expect from a romantic comedy, but the stars of I Love Trouble struggled to get along off-camera. They lacked the chemistry needed to make it work on-screen and couldn't get along, so they had to "shoot some of their scenes separately."

5 Woody Allen And Mia Farrow (Husbands And Wives)

Though Farrow and Allen had been in a relationship for twelve years, they frequently collaborated on-screen. Husbands And Wives saw the pair portray a married couple, Judy and Gabe, who ultimately separate. Woody Allen has been the topic of scrutiny for several years, but even more so after the release of the HBO docuseries: Allen V. Farrow.

Allen V. Farrow details Allen's alleged inappropriate relationship with Farrow's teenage daughter Soon-Yi Previn and the accusations of sexual abuse by his then seven-year-old daughter, Dylan Farrow. The allegations have understandably ended Allen and Farrow's professional and personal relationship, with Farrow seeking legal action soon after.

4 Tony Curtis And Marilyn Monroe (Some Like It Hot)

Though Tony Curtis and Marilyn Monroe had been involved in an affair (according to Curtis' memoir, American Prince) while they were both married, the two had been in a relationship before filming Some Like It Hot.

Curtis previously mentioned Monroe's unprofessional behavior while filming with examples of her showing up late and drinking on set. It's not hard to believe that two actors who shared so much chemistry on-screen (and off) would have some struggles and complications in their working and personal lives.

3 Sophia Loren And Marlon Brando (A Countess From Hong Kong)

Sophia Lorena and Marlon Brando in A Countess From Hong Kong

Charlie Chaplin's A Countess From Hong Kong featured two of the biggest stars of the time, Sophia Loren and Marlon Brando. Though their relationship on-screen was very romantic, the two didn't exactly share the same sentiments as their characters off-screen.

Brando likely upset Loren when he looked at the art in her dressing room and called her "mentally disturbed." In addition to their snide remarks back and forth, Brando commented on her breath after a kissing scene, claiming her breath was "worse than a dinosaur's."

2 William Baldwin And Sharon Stone (Sliver)

William Baldwin and Sharon Stone in Sliver

The filming of Paramount's Sliver was a production nightmare - from pre to post-production, the issues never seemed to stop. Such was the case with Sliver's two leads, William Baldwin and Sharon Stone. The film was meant to be a provocative thriller that Paramount hoped would garner as much box office success as Stone's previous work, Basic Instinct. 

Unfortunately, Sliver failed to gain the praise of critics and audiences. Baldwin and Stone have been tight-lipped about their off-screen tensions but Sliver director Phil Noyce said that the two weren't getting along from the start, failing to convince audiences of their chemistry.

1 Debbie Reynolds And Gene Kelly (Singin' In The Rain)

Debbie Reynolds and Gene Kelly in Singin in the Rain

The release of Singin' In The Rain was a monumental moment for both musicals and the history of film. The musical movie is set in the time when actors had to switch from silent pictures to "talkies." The two main characters become involved in a heartwarming romantic relationship, portrayed by Debbie Reynolds and Gene Kelly.

Where Gene Kelly is involved, intricate dance numbers were bound to follow, and Reynolds has stated how her co-star's perfectionist attitude made filming Singin' In The Rain brutal. Kelly, a professionally trained dancer, was doubtful of 19-year-old Reynolds' dancing skills and constantly "criticized everything [she] did."
