Jessica Biel says Colin Farrell has a "kind of magnetism" which attracts people.

The 30-year-old actress loved working with the reformed hellraiser on new sci-fi movie Total Recall, Jessica - who is engaged to Justin Timberlake - believes people are drawn to Colin simply because he is excited about life, rather than because of his partying and womanizing reputation.

"The thing about Colin is he is just so respectful and such a good guy. When you meet him the sparkle is more about having a curiosity of life, excited about the world and excited about what they're doing or traveling, it's that kind of sparkle. It's that kind of magnetism that I feel he puts out there in the world, he's just cool to be around."

Total Recall is in theaters now.
