Actors that were said to be the next big thing, but weren't

Loren Dean: With only a few credits, got the lead role as the title character in Billy Bathgate- opposite Nicole Kidman, Dustin Hoffman, and Bruce Willis. Got one other lead role in the movie Mumford, but supporting roles and guest starring parts soon followed (Enemy of the State and Bones, among others). But hasn't been onscreen since 2011.
