Model-actress Cara Delevingne says she was devastated when she failed to land the lead role in Tim Burton's Alice in Wonderland.

The 24-year-old model-and-actress thought she was the perfect match for the titular role – which went to Mia Wasikowska – in Tim Burton's movie in 2008 but was devastated when she found out that she hadn't made the cut, reported OK! magazine.

"I was disappointed I didn't get it. I was 16, that was one of my first big auditions and I was so sure it was right for me. I thought I was made for Alice but evidently I wasn't.

"It was a hard lesson but it sort of propelled me towards what I'm doing it now; it was the precursor motivation," Delevingne says.
