(Cover) - EN Showbiz - Jake Gyllenhaal says the only way to be successful at Wii Tennis is by listening to Whitney Houston.

The 30-year-old US actor has spoken about how he winds down while shooting films. He enjoys playing the sports-based computer on movie sets, and makes the game extra special by singing Whitney Houston tracts while taking part. He finds that satisfies his urge to sing in public, which he is often too nervous to do.

I dont really do karaoke that much! Whats that song I Just Wanna Dance With Somebody? I always want to do The Bodyguard soundtrack I Will Always Love You. I like that, he said when asked what his signature karaoke songs were. No, maybe just a bit of Wii tennis [on set], while Im singing Whitneys I Will Always Love You. Thats the only way to do it really. You cant play Wii tennis when youre not listening to Whitney Houston.

Jake is currently promoting science-fiction thriller Source Code, which recounts the story of a soldier who wakes up to find himself in the body of an unknown man and learns he is part of government experiment.

The Hollywood star says he came to work with director Duncan Jones on the project after sending him the script, oblivious that Duncan would actually be interested in the screenplay.

Hes amazing. I had a general meeting with him because he was interested in me playing a role in one of his movies that he was writing and then at the end of the meeting I was like, I think you should read this script, I dunno whether youd be into it, he was like Sure man, yeah, Ill take a look, he explained to Collider.com. I sent it to him and I had literally no idea hed wanna do this. I figured hed want to do something he wrote himself, cos thats what he does, but he wanted to do it which was crazy, it was awesome. Four months later we were making a movie and it was a dream come true.

The critically-acclaimed star says his most popular movies include Donnie Darko, Jarhead and Brokeback Mountain. Donnie Darko was Jakes second major film and was not a box office success upon its initial 2001 release, but eventually became a cult favourite.

I would say definitely Donnie Darko is number one. Donnie Darko fans are the most adventurous, and seemingly the most confident, then its a toss-up between Jarhead and Brokeback Mountain, he said. (C) Cover Media
