The artistic director of the Venice Film Festival, Alberto Barbera, has revealed some emotional moments he witnessed from Lady Gaga and Scarlett Johansson. According to Barbera, Gaga refused to enter the theatre during the festival's opening last year because she wanted to sign autographs for her fans. Barbera also recalled Johansson's premiere screening of "Under the Skin," which was booed by the audience but later became a cult classic. Both Gaga and Johansson have had successful careers in film, with "A Star Is Born" and "Under the Skin" being critically acclaimed.
