Recently '80s actor Corey Haim noted that he was offered River Phoenix's part as Chris Chambers in the 1986 movie, "Stand By Me." He chose, instead, to play the title character in the drama, "Lucas." My mind is boggled at what might have been! That would have meant the two Coreys in "Stand By Me, " River Phoenix would have been robbed of the role of a lifetime, and who would have played geeky but loveable Lucas? My guess is that Patrick Dempsey would have landed the part.
