Principal photography began April 6, 2009, at the Pasadena Masonic Temple, with the working title "Rasputin". The bulk of the production took place at Raleigh Studios, though other locations were also used. Scenes were filmed at Edwards Air Force Base from May 11 through May 13. The location had also been used for "Iron Man", and Favreau stated that he felt the "real military assets make the movie more authentic and the topography and the beauty of the desert and flightline open the movie up". The Historic Grand Prix of Monaco action sequence was shot in the parking lot of Downey Studios, with sets constructed in May and filming lasting through June. Permission to film in Monaco prior to the 2009 Monaco Grand Prix had initially been awarded, but was later retracted by Bernie Ecclestone. The filmmakers shipped one Rolls-Royce Phantom there, and filmed a track sequence in which race cars were later digitally added. Tanner Foust took on the role of driving Stark's racing car. Also in June, it was reported that John Slattery had joined the film's cast as Howard Stark. Olivia Munn was also cast, in an unspecified role.
