After making a very successful return to the big screen last year, for the first time in over a decade, things are progressing nicely for the upcoming The Muppets sequel.

We heard last week that Christoph Waltz is in advanced talks to star in the sequel as an Interpol inspector, and now more news has made its way online surrounding the second film.

Collider got a chance to speak to producer Todd Lieberman, who told them that the sequel will be shooting here in the UK at Pinewood Studios, with filming set to begin in late January through until April, in and around London.

After Bret McKenzie brought home an Oscar for the film for his song, Man or Muppet, the singer/songwriter is set to return to write new songs for the film, which is excellent news.

Lieberman also teased the possibility of a new Muppet, and said that we can expect a lot more casting announcements to come very soon, following last week’s news of Waltz’s involvement.

The Hollywood News are also reporting that director James Bobin, who is returning to the director’s chair having helmed the first film, was recently spotted outside St. Paul’s Cathedral in London, potentially scouting locations for the coming film.

The interior and exterior of the building have been used in a number of films and TV shows over the years, including Doctor Who, Mary Poppins, Harry Potter and the Prisoner of Azakaban, and Guy Ritchie’s Sherlock Holmes. Naturally, it’s one of the most iconic buildings on our shores, and perhaps one of the most well-known in the world, and it would be great to see it on the big screen with The Muppets for company.

Nicholas Stoller has returned to write the script alongside Bobin, and though Jason Segel has said that he’s not going to be involved in the sequel, we’re hoping that he might still be returning for a cameo.

The Muppets sequel is currently set for release on 20th December, 2013, just in time for Christmas. Given what Lieberman has said, we can expect to hear more casting news very soon. More as we get it.
