Terminator star Arnold Schwarzenegger has revealed he never expected to be back in the latest movie in the blockbuster film franchise.

The star, who shot to fame as the merciless assassin in the original film, stars alongside Matt Smith and Game Of Thrones star Emilia Clarke in the fifth film in the series Terminator Genisys.

He told Graham Norton: "I was excited about the new film but I thought they might switch me for someone new, like they do in the James Bond films, so I was happily surprised to be offered the role. It was fun to get back into shape and in to the character - it was like riding a bike and I got straight back into it."

The other guests on tonight's show include Hollywood star Jake Gyllenhaal who revealed his acting career's unlikely start - playing a cat in one of his sister Maggie's pet projects.

The Brokeback Mountain star, who is about to play a boxer in new movie Southpaw, said he started performing as a child.

He said: "My sister would sing songs from Cats and make me lick a bowl of milk like a cat in the corner of the room. And she would say, 'You're not doing it right.''
