Can't say the ad helped because the job that Corey Haim landed is Lost Boys 2 according to what the writer
Hans Rodionoff told MovieHole:
“Sam Emerson was in the earliest drafts of the screenplay, and when it looked like we weren't going to be able to cast Corey Haim, I begrudgingly took the scenes out and wrote around the holes. Recently, I got a call that said that Corey would be able to do the scenes, and Warner Bros. was happy enough with the movie that they felt like spending a little extra to work Sam Emerson into the movie would be money well spent. So, I dug back into my old files and found the deleted scenes with Sam Emerson and sent them to PJ. I really feel like Sam Emerson is a crucial part of the Lost Boys legacy, and I'm glad that his scenes will end up in the film.”
I had seen rumors that they were reshooting scenes of Lost Boys 2 with him, but I didn't want to post it until someone attached with the movie confirmed it. Personally I think if he said no to them the first go around, they should have said no to him when he said yes. I am kind over him after watching him on The Two Coreys.
