Tom Cruise and Cameron Diaz on South Boston set

Tom Cruise and Cameron Diaz, currently in Boston filming the soon-to-be-renamed "Wichita" project, are shooting near the Blue Wave bar & lounge located 343 Congress St. in South Boston's Fort Point Channel neighborhood on Monday, Sept. 28.

The Boston Fire Museum, located at 344 Congress St., served as the exterior scene's backdrop which involved Diaz and a MBTA bus. Filming moved inside the museum as the day progressed.

Both Cruise and Diaz were wearing the same outfit from last week's shoot inside the classic Parisian brasserie Gaslight located at 560 Harrison Avenue in the up-and-coming SoWa district of the South End suggesting a continuation of the same scene.

The untitled "Wichita" project follows Cruise as a secret agent who pops in and out of the life of a single woman played by Diaz.

Principal filming for the made-in-Boston spy flick "Wichita," starring Cruise, Diaz, Maggie Grace and Marc Blucas, kicked off on Tuesday, Sept. 15 at the Worcester Regional Airport.

Also, Paul Dano, known as the brooding brother in "Little Miss Sunshine" and star of Spike Jonze's upcoming "Where the Wild Things Are," has signed on to play a "charming but mysterious scientist" in the soon-to-be-renamed "Wichita" movie with Tom Cruise and Cameron Diaz.

Apparently, Dano's character is thrust into the action when his invention becomes the focus of Cruise and Diaz's chase.

Meanwhile, Loaded Gun Boston reader Vassili Shields shot the on-set photo below from a Congress Street office building.

According to Shields, "Tom was really nice and kept meeting fans. Cameron was sweet and waved to fans a lot."
