Knightley, who cites Sutherland's 1973 movie DON'T LOOK NOW as one of her favourites, also stunned her parents when they learned their daughter would be working with the Canadian actor.
The 20-year-old, who co-stars with Sutherland alongside ROSALIND PIKE, JEAN MALONE, Carey Mulligan, Brenda Blethyn and Talulah Riley, says, "Well one of my favourite films is Don't Look Now so working with him was totally terrifying.
"My mum and dad were like, 'He's the legend!'
"But we had three weeks of rehearsal before we started shooting and he just clicked with everybody. And I suspect Donald really liked being surrounded by six women."
