California (BEL): Horrible Boss Jennifer Aniston was back in Leicester Square tonight for the world premiere of sequel Horrible Bosses 2. The former Friends star returns to her role as addicted dentist Julia in the comedy and said no matter how raunchy the role got, she was happy to play it. She said: ‘I don’t think with Julia anything is too much, I’ve got to be honest. If anything I said ‘Go as far as you can’.  ‘It was just so fun - when you have an opportunity like that, you’ve got to just go for it.’ The film is Aniston’s first sequel and she explained why she was tempted back. She said: ‘The first one, I loved that time, and the part was over so soon. I was really thrilled to be able to play more of Julia because I wasn’t finished yet.’
