John Cusack hates modern technology.

The actor - who stars in the new comedy 'Hot Tub Time Machine' where he plays a character who goes back to 1986 with a group of male friends - admits he "forces" his pals to meet him for coffee because he doesn't believe technology is capable of maintaining a friendship.

He said: "Sometimes I say to my friends, 'We have to go out and have coffee together or something, because I'm tired of just talking in email and texts. I want to make sure it's really you.'

"You know what I mean? I force people to have coffee with me, just because I don't trust that a friendship can be maintained without any other senses besides a computer or cellphone screen."

The 43-year-old star said making the movie had made him realise how much everyone relied on technology such as micro-blogging website twitter to keep in touch nowadays, even when it came to romance.

He said: "As long as you can tell somebody how you feel in 140 characters or less. It's exhausting. I don't know, I don't think any of that really counts, you know?"

He added: "That's a great line in the film, where Jacob - played by Clark Duke - is hitting on a girl in the 80s and he says to her, 'How can I get in touch with you later?' And she says, 'Well, you're going to have to come out and find me!' "
