剧情简介：Like all movies, a test is filmed of a performer considered for a starring role. Alfred Hitchcock had to do this for Anny Ondra, a German actress who was cast in his first talkie- BLACKMAIL. Here we see Hitchcock, about 30 years old, with a head of wavy hair, test Ms. Oondra's recording voice by asking her naughty, embarrassing questions. You can either say; "Ewww! The pig!" or you can say "Okay, two pals having a laugh." Of no historic importance, has no insight to the Hitchcock style- just very interesting.
