WATCH out for muppets in Greenwich this weekend - as the children's favourites film their new movie.

Part of the Old Royal Naval College is being transformed into Berlin for the film's set.

Due out next year, The Muppets...Again! will feature Ricky Gervais, Tina Fey and Ty Burrell.

It will see Kermit and pals travel around Europe while being trailed by the world's top criminal.

The college, a setting for Oscar-nominated Les Miserables, saw nearly 1.8m visitors last year, making it one of the UK's most popular tourist attractions.

And the muppets' visit follows hot on the heels of Nicole Kidman, who filmed in the park this week.
