Frontier of the Stars is a lost 1921 American drama silent film directed by Charles Maigne and written by Charles Maigne and Albert Payson Terhune. The film stars Thomas Meighan, Faire Binney, Alphonse Ethier, Edward Ellis, Gus Weinberg and Florence Johns.
Buck Leslie (Meighan) is a gangster who is embroiled in a barroom brawl and mistaken for a killer. He climbs to a rooftop in order to evade the police and finds Hilda Shea, an innocent, wheelchair-bound girl (Faire Binney). Hilda's sheltered life consists of her tenement home and its rooftop. Leslie easily convinces the girl that he is merely playing a game and she willingly sends the pursuing cops away. A friendship develops between the crook and the invalid, and it brings out the best in Leslie.
