THE LINE-UP was one of those movies which went missing for a long time until it turned up where it was not expected -- confused for a kinescope of a episode of a TV series by the same name. It has a good story, interesting staging, and terrible acting.
First, let's talk about the sound. With the rise of sound in movies, there was competition between the Warner Brothers Vitaphone sound system, and William Fox's Motivetone. Eventually the latter won out, but in the meantime, other systems arose. Long-time producer Pat Powers bought a system, named it 'CInephone', and tried to interest producers in it. Its only well-known use was in Ub Iwerks' cartoons, which, not coincidentally, were produced by Powers. The system was also used in this movie, the first and only effort of a projected series of a dozen shorts.
It's not easy to tell what the end result was at the time, but the sound track as it exists is buzzy and patchy. The actors' voices are no help, because they all speak stagily, and some, like Viola Richards, are nearly inaudible. Certainly, the Iwerks cartoons had good sound, but those were recorded separately from the images. Whether the poor sound quality is an artifact of the recording or the copy of the movie is impossible to tell. To put it kindly, it does not impress, and its hand lies heavy on the movie as a whole.
None of the performers had a major film career after this. Miss Richards had appeared in several Hal Roach shorts a few years earlier, and she was a competent comedian in them.
The IMDb trivia for this movie states that Miss RIchards made no further sound films. That is wrong. A consultation with her IMDb filmography will show she would appear in a coupl of Roach shorts in 1935.
