This Spring Channel 4 will be brightening the schedules with a generous helping of comedy.

From the creators of the BAFTA-winning Fonejacker comes Facejacker. Man of mystery Kayvan Novak brings new and familiar characters to life with the aid of prosthetics, and unleashes them on an unsuspecting public.

Channel 4's Comedy Gala brings together some of the nations' best-loved comedians for a two-hour extravaganza in aid of Great Ormond Street. Alan Carr, Bill Bailey, Jack Dee, Jonathan Ross, Michael McIntryre, Sean Lock and Rob Brydon are just some of the names coming together for the biggest stand-up show in UK history.

Also, hosted by Jimmy Carr, Channel 4 brings the US format of the 'Roast' to our screens. Each week a famous face is subjected to a 'roasting' by friends and colleagues. The tone is affectionate but also cutting and mischievous. Sharon Osbourne, Bruce Forsyth and Chris Tarrant will all be proving they have a thick skin as they take to the stage in front of the 'roastmasters' and a live studio audience.

A brand new live entertainment show also hits our screens in April. Filmed live at a secret location, The Money Drop will see contestants given £1million a night... all they have to do is play the game and keep hold of their cash. In addition Alan Carr: Chatty Man, The IT Crowd, You Have Been Watching, Comedy Lab and Bremner, Bird and Fortune all return with new series.

From the science department comes one of the most ambitious television projects ever undertaken. In Plane Crash (working title) two highly experienced pilots board a passenger jet, fly it out over a vast, empty desert, set it on course to crash land - and parachute from the plane. All that will be left on board are a raft of cameras, crash test dummies and scientific instruments which will give an unprecedented insight into exactly what happens when planes crash.

The Genius of Britain brings together a formidable co-presenting team of Richard Dawkins, James Dyson, Stephen Hawking, David Attenborough and Robert Winston to celebrate the nation's rich scientific heritage.

The second series of Heston's Feasts takes inspiration from the world of literature as chef Heston Blumenthal creates banquets based on his favourite childhood stories including Charlie and Chocolate Factory, Snow White and Frankenstein. Fellow chef Jamie Oliver travels across Europe and North Africa in search of authentic ingredients and extraordinary characters in Jamie Does... and Iron Chef comes to the UK with teams of culinary challengers competing against resident Iron Chefs Tom Aitkens, Martin Blunos, Judy Joo and Sanjay Dwivedi in the ultimate cook-off.
