Hot House Superstar Francesco D’Macho brought his deeply sexy energy and charisma to the set of Trunks 4: White Heat in Palm Springs. Day 3 paired the international sensation with Christoph Scharff and judging by the intense connection the two had on set, this scene will be a highlight of the movie. The crew worked nearly 15 hours yesterday in the blistering heat, starting at 7 AM and finishing with some playful underwater filming after sunset. Check out these photos to see what happened throughout the day, including how the crew rigged the camera to the front of a shiny new silver Corvette, Colby Taylor’s birthday cake, and the sizzling scene between Francesco and Christoph.
