Carey Mulligan's parents thought she was lying about working with Dame Judi Dench.
The British actress - who first found fame when she starred alongside the legendary actress, Keira Knightley and Rupert Friend in 2005's 'Pride and Prejudice' - struggled to convince her parents she would be working with famous co-stars.
She told Britain's The Times newspaper: "I told them, 'So, I'm going to be in this film with Judi Dench,' and they thought I'd made the whole thing up."
