This is a mildly amusing satire on the way that actors were and are so idolized by the public. Johnny Arthur stars as a young man trying to impress his girl, who herself seems preoccupied with collecting autographed pictures of all her favorite movie stars. There is not much of a story, but it does have a point of sorts to it, and there are some entertaining moments.
Most of the movie has Arthur trying to dress and act like some of his girl's idols, and Arthur is not a bad mimic. His impressions usually include a couple of clever moments, although otherwise there is not a lot going on.
Perhaps the most interesting aspect of "My Stars" is that it was one of the features that Roscoe Arbuckle directed (and may have written - on the print as it now exists, there is no director or writer credit) while he was blacklisted. Given the way that he was treated, it would have been easy for him to have a much more bitter view of the movies, but the tone here is instead light and upbeat.
