Stick em up! Josh Duhamel looks armed and dangerous on the set of Transformers

Josh Duhamel has joined the set of the new Transformers movie and the 37-year old actor got stuck right in shooting one of his many action sequences.

Wearing an all black military uniform and toting a large machine gun the handsome star looked every bit the action hero as he reprises his role of Major Lennox.

The star filmed on the set in a closed of part of central Chicago which has been made to look completely destroyed with overturned burnt out cars and piles of rubble. At one point he waved at waiting fans in-between takes.

The day before, Shia LeBeouf, 24, and Rosie Huntingdon-Whiteley, 23, filmed their scenes for the film on the same set location.

They sprinted through piles of rubble and concrete as they filmed a fast paced scene surrounded by over turned cars and blown up statues.

British lingerie model Rosie, who is the face of Victoria's Secret, was signed up to star in what is thought to be the final instalment in the film series after Megan Fox decided to opt out.

The sci-fi action movie franchise is a hugely-successful reboot of the much-loved Eighties kids' cartoon in which cars and other vehicles can change, or transform, into robots.

The film began shooting in Los Angeles last week before heading to Chicago and then on to Florida, Milwaukee, Indiana and then back to LA.

The third movie also sees the addition of Patrick Dempsey, John Malcovich and Frances McDormand to the cast.
