"It's a movie about the exploration of a relationship over five years. Emily Blunt and I have been friends for about five years and that's why I wrote it for her," he said.

The best part of being a writer? Brainstorming love scenes with his leading lady.

"I love that... and she shows up and just has to do it," he said to Today co-anchors Al Roker, Matt Lauer, Ann Curry and Natalie Morales.

When the topic of Jason's habitual onscreen nudity was broached, he quipped: "I'll tell you what's a shame... apparently me being naked is funny," he said. "Onscreen, in my personal life... if I take my clothes off, it's met with hysterical laughter."
