The new Muppets film, The Muppets... Again! will have a retro feel, as it harks back to the 1960s. Joining the crew of cotton-based favourites are Ricky Gervais, Tina Fey and Ty Burrell.

"It's a tip of the hat to the old-school crime capers of the '60s, but featuring a frog, a pig, a bear and a dog - no panthers, even pink ones - along with the usual Muppet-y mix of mayhem, music and laughs," the film's director James Bobin said in a statement. Gervais will play the sidekick to villain Constantine; Fey will assume the role of prison guard Nadya. And Modern Family actor Ty Burrell will play an Interpol agent. Sounds like fun. The Hollywood studio in charge, Walt Disney, said "The Muppets ... Again!," a follow-up to "The Muppets," is set to be released in theatres on March 21, 2014.

Bret McKenzie will once again be on musical duties - he won an Oscar for his song 'Man or Muppet' for the last film. 'The Muppets' made more than $100 million at the global box office, so the sequel will have a lot to live up to, but given the popularity of the characters, and the star-added value in Gervais, Fey and Burrell, we're sure it'll trump all Muppet records.
