Actor George Clooney has got back to work for his upcoming movie `Tomorrowland` three weeks after his marriage with British advocate Amal Alamuddin.

Clooney tied the knot with Alamuddin in a lavish Italian ceremony Sep 27 and three weeks later, he was back filming for his new film in Vancouver, Canada.

Dressed in a pair of dark-green corduroys and a khaki zip-up jacket, the actor was spotted when he took a break from shooting to grab lunch, dailymail.co.uk reports.

The film, which also stars Hugh Laurie and Britt Robertson, is the orchestration of Brad Bird, who has also directed `Mission Impossible: Ghost Protocol`.

Damon Lindelof, producer of "Tomorrowland", along with Bird and Clooney revealed a first look trailer of their super discreet sci-fi mystery at New York Comic Con.

The feature is due to hit cinemas in May 2015.
