OT: Steve Jobs did not like Iron Man 2.

On August 31, 2009, The Walt Disney Company announced a deal to acquire Marvel Entertainment for $4.24 billion, with Marvel shareholders to receive $30 and approximately 0.745 Disney shares for each share of Marvel they own. The voting occurred on December 31, 2009 and the merger was approved. The acquisition of Marvel was finalized hours after the shareholder vote, therefore giving Disney full ownership of Marvel Entertainment. The company was delisted from the New York Stock Exchange under its ticker symbol (MVL), due to the closing of the deal.

Principal photography began April 6, 2009,[75] at the Pasadena Masonic Temple,[76] with the working title Rasputin.[77] The bulk of the production took place at Raleigh Studios,[74] 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".[78] The Historic Grand Prix of Monaco action sequence was shot in the parking lot of Downey Studios, with sets constructed in May[79] and filming lasting through June.[80] 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.[81] Also in June, it was reported that John Slattery had joined the film's cast as Howard Stark.[38] Olivia Munn was also cast, in an unspecified role.

A massive green screen was constructed at the Sepulveda Dam to film a portion of the Stark Expo exterior, with the rest either shot at an area high school or added digitally. To construct the green screen, hundreds of shipping containers were stacked, covered in plywood and plaster, and then painted green. For the conclusion of that climactic scene, which the crew dubbed the "Japanese Garden" scene, a set was built inside Sony Studios in Los Angeles. Filming lasted 71 days, and the film's production officially wrapped on July 18, 2009
