Claim: Will Turner is the son of a fictional man.

William `` Bootstrap Bill '' Turner Sr. is a fictional pirate in Disney 's Pirates of the Caribbean film series . Although he is only mentioned in the first film , he appears in the first two sequels , portrayed by Stellan Skarsgård .   Marine flora and fauna encrust Bootstrap as he is gradually transformed by the aquatic environment in which he now lives . The longer anyone serves aboard the Flying Dutchman , the more his human-like features become extinguished as they are replaced by sea life . Bootstrap 's humanity remains more visible than those of the other crew members ; presumably he is one of the most recent additions to Davy Jones 's crew .   `` Bootstrap Bill '' Turner was the only member of Jones ' crew that was not created digitally . His appearance was achieved with prosthetics and makeup .
