Rhys Ifans likes befriending people who are "hard as f**k" and live in "dodgy areas".

The 'Mr Nice' actor gets a huge "rush" by walking through dangerous districts of cities and talking to the locals who live there.

He said: "My kind of dangerous sport is to arrive at a place - wherever it may be - and find out about where the dodgy area is, where the people are hard as f**k, and go there on my own. I do get a rush, especially if people don't know who you are."

The 43-year-old star loves this type of "sport" and admits credits it for some of the best nights out he's ever had.

He explained: "People think 'This guy must be f**king mad' and you sit down and you strike up a conversation and I have some of the best nights of my life in some of the most dangerous places in the world."

However, this doesn't always go to plan, and Rhys has narrowly avoided serious trouble on several occasions.

He added to FHM magazine: "I've had a few scrapes in places like Morocco, Uruguay, Thailand. I have got a gypsy gene."
