Heath Ledger and Michelle Williams' love 'a gift'

For the producer of Brokeback Mountain, a real-life romance between Heath Ledger and Michelle Williams was a gift.

The film stars Ledger and Jake Gyllenhaal as ranch hands who fall in love, then hide their affair from their wives and families for years. Williams, best known for her years on Dawson's Creek, plays Ledger's wife, Alma.

"It was a big gift to have two people falling in love in our midst," producer James Schamus said. "You forget how lovely that is."

The couple are engaged and recently had their first child, Matilda.
