Late TARZAN star Johnny Weissmuller's dying son has launched a lawsuit to regain possession of his father's famous loincloth. Weissmuller, who was a five-time Olympic gold medal-winning swimmer before turning to acting, donated the famous item of clothing along with his medals to the Swimming Hall Of Fame in Florida in the 1960s. But his terminally ill son JOHNNY JR is desperate to include his father's heirlooms in his children's inheritance before he passes away. His wife DIANE says, "They have no legacy, nothing of their grandfather's. We want what belongs to the family. "(We will put the items on display) - Johnny Weissmuller belonged to the world." But Swimming Hall Of Fame boss BRUCE WIGO says, "Johnny said this was where he wanted his memorabilia. His legacy is best preserved here." Weissmuller won his Olympic medals at the 1924 and 1928 games, and broke more than 50 world records before starring in 12 Tarzan films in the 1930s and 1940s.
