Harry Potter: Behind the Magic (Saturday, ITV1, 7pm) You can run, but you can’t hide from Harry Potter.

The sixth film in the franchise, Harry Potter and the Half-Blood Prince, is set to be released. No doubt millions of fans of the boy wizard will be rushing to see it.

To get them in the mood, ITV1 is broadcasting this special programme, hosted by Ben Shephard, which takes an exclusive look behind the scenes of the production.

Ben even gets a chance to be an extra — although whether you’ll recognise him remains to be seen.

”It was so exciting to be a part of it and even though I’m only in for a few seconds, I was there and I can show my kids it,” says Ben. “As a fan and as a movie lover it was a really special moment.”

Plus, there’ll be a chance to get a sneak preview of eye-popping scenes from the new movie, while Ben also catches up with stars Daniel Radcliffe, Rupert Grint and Emma Watson.

Michael Jackson’s Last Days: What Really Happened (Sunday, Channel 4, 9pm) The world has gone Michael Jackson crazy in the few days since his tragic death.

Millions of column inches have been devoted to his memory, and his records are flying off the shelves like never before.

Reviled and loved in equal measure, he was a true cultural icon who, if anything, looms larger than ever before.

But chances are that, years from now, people will still be discussing what happened in the last days of his life and, most importantly, could his death have been avoided?

Already, conspiracy theories are circulating. In this must-see documentary, Jacques Peretti examines the final four months of the singer’s life and the events leading to his death.

The reporter delves behind the scenes of the star’s proposed comeback concerts and personal life as he tries to piece together why the seemingly fit and healthy performer died unexpectedly.

The Great London Jump: Robbie Maddison (Monday, Five, 7.30pm) Robbie Maddison appears to be a brave fellow, not least because he is described by Five as being a “daredevil stuntman and motocross star” — that gave us a small hint.

However, if you need any more convincing, just cast your eye over some of his previous feats. He’s jumped the length of an American football field and scaled the heights of the replica Arc de Triomphe in Las Vegas.

Now, he’s come to do a leap in London. The location will be revealed before broadcast. We’ve been told: “To pull it off, the stunt will require intense planning and nerves of steel as the fearless biker rides out into the unknown.”

In 2007, Robbie travelled 98 metres through the air over a football field and the following year he smashed his own record. Twice. He set a final distance of 106.9 metres.
