Production on Season 2 of DC Universe's original action drama Titans may be getting delayed.

According to GWW, the show will not begin filming until April 2, rather than March 20, as was originally planned. The report also suggests production Stargirl, which is slated to arrive on the streaming service later this year, has also been delayed.

It's unclear why production has been delayed on Titans, but it's possible that it's related to casting, as the series is reportedly adding several new characters to Season 2, including Deathstroke, Ravager, Jericho and Lex Luthor.

On other fronts, there is good news. Doom Patrol is getting two more episodes and has reportedly already been greenlit for a second season. Meanwhile, work on the James Wan-produced Swamp Thing is still in full swing, with the production currently filming episode six. Swamp Thing is also expected to hit the service later this year.

Titans Season 2 does not currently have a set premiere date, and it's unclear if a delay this minor would have affect any that the streaming service had in mind.
