There’s no doubt that Katy Perry is popular, becoming the only artist ever to spend more than a year in the US Billboard Top 10 (although admittedly with different songs). Now she’s coming to cinemas with the concert movie/documentary, Part Of Me, which looks at her life and loves, as well as her music. Indeed fans are being offered the chance to be involved of the film, engaging with Perry’s Twitter account to help choose which songs Katy will sing, and weigh in on her wardrobe options for the film. The film will be out later this year.

Does Keith Lemon need a movie? He may be a bit of a Marmite act, but there’s no doubt he has a large amount of fans, with Leigh Francis’ creation finding success on everything from Celebrity Juice to This Morning. Now the first trailer from his upcoming movie has arrived, which sees him in bed with Kelly Brook! Here’s the synopsis: ‘Keith Lemon The Film is a comedy about Keith following his dreams of becoming a successful entrepreneur, just like his hero Richard Branson. He comes to London from Leeds, becomes an overnight billionaire then an over day failure before finding the road to redemption. In cinemas, August.’

Although Scarlett Johansson’s Black Widow was introduced in Iron Man 2, she didn’t have an awful lot to do in the movie. However she’s back in The Avengers, and along with Jeremy Renner’s Hawkeye, is the major character we’ve see least of. It’s not surprising therefore that the first official clip form the film is dedicated to her, showing they she can kick ass with the best of them and that this won’t just be a testosterone fest (assuming Asgardgian gods like Thor have testosterone, of course). Here Black Widow/Natasha Romanova being called into action by S.H.I.E.L.D.’s Agent Coulson. The film hits UK cinemas on April 26th, when Black Widow will be joined by Iron Man, The Incredible Hulk, Thor, Captain America, Hawkeye and Black Widow.

It took a while to get a film version of the classic 70s TV show, The Sweeney, off the ground, but now it’s on it’s way, with Ray Winstone and Ben ‘Plan B’ Drew taking on the roles made famous by John Thaw and Dennis Waterman. While the 70s show was known for being a gritty take on the cop drama, it seems the film will be adding a whole new level of grit, with Winstone’s Jack Regan a hardened, take no prisoners cop, working alongside Drew’s newbie officer. It’ll be in cinemas in September.

After the wonderful Midnight In Paris last year, it’s fingers crossed that Woody Allen can continue his winning streak while simultaneously continuing his European tour, this time heading to Italy for To Rome With Love. The trailer doesn’t exactly make the plot clear, although it will follow a number of people in Italy, some American, some Italian, some residents, some visitors, and the romances and adventures and predicaments they get into. Woody stars alongside Ellen Page, Jesse Eisenberg, Penelope Cruz, Alex Baldwin and Roberto Benigni. No UK release is currently set, but it’ll be out later this year.

For a while it looked like Whitney Houston was getting her life back on track and she even planned a return to cinemas, shooting a role in Sparkle (as well as producing), which is her first film since the TV movie Cinderella in 1997. The movie is out in October, but sadly Houston never lived to see it. A remake of a 1976 movie, the film tells the story of the title character; Sparkle (Jordin Sparks), the youngest of three sisters and a music prodigy who struggles to becomes a star while overcoming issues that are tearing her family apart. Sparkle is from an affluent Detroit area, naive to the unexpected experiences her new life will bring as she and her two sisters blossom into a dynamic singing group during the Motown-era. Houston play’s the trio’s mother, Emma. It all looks very Dreamgirls, but could be good fun.
