Great expectations as Jennifer finally finds a best friend in Justin

But Justin is different.

Rather than having conventional leading man looks, he is darker and more brooding.

He has cool Indie roots, being part of the Theroux clan – as the nephew of the travel writer and novelist Paul Theroux, and the cousin of quirky TV presenter Louis, famous for his compelling documentaries.

He cut his teeth as an actor with small parts in shows like Sex and the City and Six Feet Under, before moving onto movies.

Among his first big film roles was American Psycho. The thriller was followed by Mulholland Drive, which he promoted at Cannes with director David Lynch and co-stars Naomi Watts (left) and Laura Harring.

Part of the draw is surely his sense of humour.

Justin co-wrote acclaimed comedy hit Tropic Thunder - a gig which led Robert Downey Jr to recommend him for the job as screenwriter for Iron Man 2
