Lionheart is a 1990 action film directed by Sheldon Lettich, starring Jean-Claude Van Damme and co-starring Brian Thompson, along with Harrison Page, Deborah Rennard, Lisa Pelikan and Ashley Johnson. Van Damme plays a paratrooper legionnaire. When his brother is seriously injured, he returns to Los Angeles to enter the underground fighting circuit and raise money for his brother's family.
The cast and crew of the film included two people who had appeared in an earlier Van Damme film: Michel Qissi (a good friend of his) and Sheldon Lettich. This was the second time that Qissi played a villain in a Van Damme film, the first being remarkably like Tong Po in Kickboxer (1989). Lettich helped write one of Van Damme's innovative films, Bloodsport, along with another Van Damme film, Double Impact. The film raised $ 24.3 million on a budget of $ 6 million.
