Thanks to the success of the Muppets movie, things have now shaken loose for the film The Happytime Murders, a puppet/human murder mystery movie that has been in development since 2008. The Happytime Murders are set in a world where puppets and people live together, but puppets are treated as second-class citizens.
When the puppet cast of an 1980s kids TV show gets murdered one by one, a disgraced detective-turned-private eye puppet takes on the case.
Brian Henson will direct, and the script is written by Todd Berger and Dee Austin Robertson. And Katherine Heigl is going to be in it for some reason.
