Plot details are being held under wraps, but we do know that Tina Fey is going to portray a Russian gulag prison guard. Ty Burrell will be playing a lazy Interpol inspector. Ricky Gervais's character is still unknown. James Bobin will be back to direct the sequel from a screenplay he wrote with Nick Stoller.
Tina Fey most recently appeared in Shawn Levy's comedy Date Night and will be hosting The 70th Annual Golden Globe Awards alongside Amy Poehler.
