This film was released under one of five titles, depending on the country it was released in. It was released under the names 'Lionheart', 'Full Contact', 'A.W.O.L Absent Without Leave', 'Wrong Bet,' and 'Leon '. The film was independently funded and so was sold to various distributors throughout the world. It is therefore assumed they just picked the title that had the most impact in their respective territories.
A trailer for the film, seen on various VHS releases from Imperial Entertainment, which produced the film, makes absolutely no indication of Universal Pictures' involvement, since Universal would only pick up the U.S. distribution rights later in the process.
