The director had to rewrite his script especially for Wilson after meeting the actor and realising he was perfect for the role of a romantic dreamer in the film.
Allen admits he had 10 Things I Hate About You star David Krumholtz in mind when he first penned the screenplay - but was swayed by Wilson.
He tells WENN, "I had written this for an East coast thoughtful person, someone who you would associate with New York or an Ivy League school; a part I might have played if I was younger. I thought of David Krumholtz playing him at one point. I couldn’t get the right person for it and then Owen’s name came up and I thought, 'Owen, you must be kidding, he’s a beachcomber. This guy’s at home with a surfboard.'
"Then I investigated him and found out he’s a cowboy; he was born in Dallas and lives in Hawaii - so this is the opposite of who I want. But he is very talented and funny and he does have a kind of melancholy streak to him. Then I met Owen and found he’s quite bright. He’s very well read and very well spoken and not at all a cowboy. I never knew it and I didn’t suspect it from his physical image."
And Allen admits he was pleasantly surprised when it came to working with the Wedding Crashers star: "He was wonderful to work with. He brought his little mutt dog with him to Paris and the dog was on the set all the time chasing after Owen and I hate dogs. I never had an actor with a dog - but he’s great."
