When Chastain tried to run a la Cruise

Actress Jessica Chastain says she got the hang of running well when her co-star Sam Worthington asked her to try and emulate Tom Cruise's style.

The 36-year-old admits she had bad form when sprinting and it wasn't until her""The Deb"" co-star gave her some pointers.

"Sam Worthington, who I acted with in 'The Debt', had to teach me (how to run), because I used to look like such a wimp when I tried. He told me to think of Tom Cruise when he runs in movies - that's what I was aiming for"" contactmusic.com quoted Chastain as saying.
