The 44-year-old actress met her spouse, 44, almost 15 years ago when they starred alongside one another in "A Beautiful Mind" but, although there was an instant chemistry, the brunette beauty believes it wasn't until she saw the actor's musical talent that she was really won over by him, reported Female First.
"I remember meeting him at the first read through. I thought, 'Hmm, he's really good, that guy.' He started playing guitar and it was all over."
Bettany said he was in awe of her beauty when he first laid eyes on her on set of the movie.
The couple, who have children Stellan, 12, and Agnes, four, together, struck up a relationship once filming had wrapped up in 2001 and they married shortly afterwards in 2003.
Connelly, who has 18-year-old son Kai from a previous relationship, and Bettany also starred opposite one another in 2009's "Creation" but their new project "Shelter" marks the first time the hunk has stepped behind the camera.
