This name is at least used by 2 quite different persons.

First there is the Australian born actor  Frank Thring (1926) known for his roles in old epic movies like:
Ben Hur, The Vikings, El Cid, King of Kings and other work. Born in 1926 see:

Secondly there is quite another person. Porn actor and director, British Frank Thring (1950) See:

http://www.imdb.com/name/nm0861931/

It would be best to be able to distinguish between both different persons. The facts about the Australian born actor are better documented so I propose to add his birth year in his profile.

Thanks
