There’s Something About Rom Coms (Channel 4, 9pm)

Rom coms might get stick, but you can’t argue with the box office figures. In this documentary, director Richard Curtis, Meg Ryan and Hugh Grant tell the stories behind their best-known romantic comedies.

Die Hard (E4, 9pm)

If rom coms aren’t your thing, you can always switch over to E4 and watch Bruce Willis taking on Alan Rickman in this classic action film.

Everybody’s talking about: Catfish

In a new episode of the MTV show, a man reveals that he believed he was dating Katy Perry for six whole years, even buying her an engagement ring with his life savings.

He believed this in spite of never actually speaking to ‘Katy’ – and also despite the real Katy being married to Russell Brand, and subsequently dating John Mayer and Orlando Bloom.

In reality, he was talking to a woman from Gloucester. Oh boy.
