Captive tigers were bred with lions to create hybrids called liger and tigon. BGI would also sequence the genomes and epigenoms of a liger and tigon. A tigon is approximately twice as light as liger. The second generation hybrids of liger or tigon are known as liliger and litigon. So natural hybridisation does not happen with the liger or the tigon. The tigon is not as common as the converse hybrid, the liger. As with the tigon, the liger exists only in captivity. The less common tigon is a cross between a lioness and a male tiger. A tigon is the offspring of a tiger and a lioness. The film was produced by Louis M. Heyward for Tigon British Film Productions. Benny U. Murdoch is loosely based on Tony Tenser, head of Tigon films. They signed a deal with Hemdale Film Corporation, which was then associated with Tigon Films. He originally wrote "Alvin Purple" for the English company Tigon Films. Midway Games collaborated with Tigon Studios to design the game. The film was produced by Leander Films and Tigon British Film Productions.
