The on-set picture shows Cooper's Chris Kyle and his on-screen wife tying the knot aboard a yacht in Marina Del Rey.
Bradley Cooper and Sienna Miller said "I do" for a movie. The two stars were pictured filming a wedding scene aboard a yacht in Marina Del Rey over weekend for "American Sniper". He donned a tux, while she wore a white strapless fishtail dress. One of the pictures showed them sharing a smooch.
Clint Eastwood directs the movie based on the true story of Chris Kyle, a Navy SEAL who came to record the highest number of sniper kills for an American. Cooper plays the main character who was dubbed the "Devil of Ramadi" by Iraqi insurgents due to his lethal skills, while Miller is tapped to play his wife Taya.
"His [Kyle] story really needs to be told, and it's also relevant on two fronts: gun control and the need to address the many soldiers who are coming back with PTSD," said Cooper who also serves as one of the producers.
