You can see a recording of just before the acid and he looks like Tommy Lee Jones, so unfortunately that doesn't work...Random theory, but I think Billy Dee's Harvey Dent might have became "Tommy Lee" when the acid thrown on his face pigmented his skin somehow. Different personalities still, but Harvey Dent always became insane after becoming Two-Face so that's less of a stretch.
Half man and half madman, Two-Face was the alias of former Gotham City District Attorney Harvey Dent. After he received brain damage by a mobster's acid, Dent became a bloodthirsty, eccentric, and homicidal maniac with a penchant for using a coin that determined all of his actions. Grissom...
