After releasing two R-rated animated movies in a row with "Batman: The Killing Joke" and "Justice League Dark," Warner Bros. Animation returned to PG-13 territory this month with "Teen Titans: The Judas Contract." However, that doesn't necessarily mean the studio is closing the door to more mature material.

“It's hard to say," producer James Tucker told ComicBook.com. "I will say this, that they have said that if the content merits the R they’ll look into it, they’re open to it, which was not something that was a part of the landscape until recently. I like having that option because there’s certain things that you just can’t do without being a little edgy, without being a little more violent.”

An adaptation of the 1989 graphic novel by Alan Moore and Brian Bolland, "Batman: The Killing Joke" was the first DC Universe Original Animated Movie to earn an R rating. The film proved divisive, receiving criticism for its portrayal of Batgirl. Released last summer, it was followed in January by the R-rated "Justice League Dark," inspired by the team of supernatural heroes of the same name created by Peter Milligan and Mikel Janin. That film was generally well-received by fans and critics alike.

Debuting digitally April 4 ahead of its April 18 release on home video, "Teen Titans: The Judas Contract" is an adaptation of the classic "New Teen Titans" storyline by Marv Wolfman and George Perez. It will be followed this summer by "Batman and Harley Quinn."
