Kate Winslet and Patrick Wilson in 'LITTLE CHILDREN'

The 31-year-old struggled while shooting a sexy encounter with her LITTLE CHILDREN co-star PATRICK WILSON, so she whisked herself back to her breakout role in the 1997 JAMES CAMERON movie to get herself through the ordeal.

She says, "I couldn't see his face so I just kept thinking that it was me and Leo all over again. That thought really helps get through it."
