Actor Tony Danza has no problems with teenagers sneaking in to see his new R-rated sex addiction movie Don Jon - because he thinks the film is very educational.

The former Taxi star teamed up with old pal Joseph Gordon-Levitt and Scarlett Johansson for the movie, and he thinks it offers lessons in love.

He says, "I think it's important for kids to see. It's a cautionary tale and there's absolutely blatant warnings in there about using condoms and about relationships. Instead of propogating bad behaviour, it's actually calling on people to go, 'Hmm, am I doing that?'.

"I watched (Mark Wahlberg and Denzel Washington film) 2 Guns the other day and I think that's what the problem is - you have movies where people are killing each other left and right. I think this is a love story. I don't see how this could be a bad influence."
