Last month, a work-in-progress version of Seth Rogen and Evan Goldberg's Sausage Party debuted at SXSW, eliciting a great response. It also confirmed a new trend: the unexpected R-rated movie.

Fandango editor Erik Davis has described the movie as "the Deadpool of animated movies, and in a riskier year where a film like Deadpool changes the game when it comes to R-rated superhero movies, Sausage Party -- depending on how it's received by audiences -- may also change the game when it comes to R-rated animated fare."

Note: trailer below is not safe for work. Sausage Party is heading to theaters on August 12.

We've been hearing about Batman: The Killing Joke for a little while now. An animated adaptation of the 1988 graphic novel written by Alan Moore and illustrated by Brian Bolland, it's the first entry in the DC universe original-movie franchise to receive an R rating. Unlike the jocular Deadpool, this is a dark and dramatic superhero tale that provides a tragic origin story for the Joker.

Kevin Conroy and Mark Hamill lead the voice cast as Batman and the Joker, respectively. The first trailer has now been released, which you can watch below; the movie will be released later this year.

Finally, we've been hearing about The Happytime Murders for years. Back in 2012, the project was described as having "a noir puppet storyline that includes a few sexy moments, a serial killer, and a detective framed for murder." The story was set "in a world where puppets coexist with humans as second-class citizens." At the time, Katherine Heigl was attached to star with Brian Henson set to direct.

Now Deadline reports that Jamie Foxx is in early negotiations to star as a Los Angeles police detective assigned to the murder case. He must work with a mismatched partner to solve the case. It appears that Katherine Heigl is no longer involved, though Brian Henson is still attached to direct.

The movie will combine live action and puppetry -- see concept art below -- and will likely earn an R rating, due in part to the debauched activity of the titular gang, puppets that are also stars of a television show. We're keeping an eye on this one to see when it might gain theatrical release.
