I have a few to add...
Tim Gibbs auditioned for the role of AW’s Joe Carlino (the character was called Joe McConnell before Joe Barbara was cast). Gibbs then was cast as AW’s Gary Sinclair….
Stephen Nichols auditioned for the role of AW’s Evan Bates (Eric Scott Woods got the part)
David Tom auditioned for the role of OLTL’s Will Rappaport (Jason Shane Scott got the part)
Then-AMC executive producer Jean Burke considered temporarily recasting Erica with Lisa Peluso when Susan Lucci was doing “Annie Get Your Gun” on Broadway and was very sick (either pneumonia or borderline pneumonia).
