“What is the derivation of in like Flynn?”

Reference books almost universally assert that this set phrase, an American expression meaning to be successful emphatically or quickly, especially in regard to sexual seduction, refers to the Australian-born actor Errol Flynn. His drinking, drug-taking and sexual exploits were renowned, even for Hollywood, but the phrase is said to have been coined following his acquittal in February 1943 for the statutory rape of a teenage girl. This seems to be supported by the date of the first example recorded, in American Speech in December 1946, which cited a 1945 use in the sense of something being done easily.
