"Vitaphoning", i.e. filming and recording using the Vitaphone system, is pictured on screen, as part of the action.
In a separately filmed trailer, Vitaphone production reel #3721, Alice White speaks to the audience about the picture.
In September 1928, Warner Bros. Pictures purchased a majority interestin First National Pictures and from that point on, all "First National" productions were actually made under Warner Bros. control, even though the two companies continued to retain separate identities until the mid-1930's, after which time "A Warner Bros.-First National Picture" was often used.In
Originally, the last ten minute reel was in 2-color Technicolor, but it only presently survives in black-and-white.
