5. The Flash - Mark Paul Gosselaar
If you read one of my
first articles on this site, then this shouldn't be a surprise to you. But, really, the early 90s were quite good for Mark-Paul, leading him to become one of the most desirable actors by the young ladies nationwide. His later 90s stuff? Fairly forgettable. But Gosselaar has always been warmly charming, funny, genuine, and quite good (especially in his new show Franklin & Bash), and his casting as Barry Allen would not only improve his own personal standing with some of the fans he may have lost, but the film itself doesn't suffer any major blows by giving The Flash, who just recently finished his own TV series, some new (and probably cheaper than his co-stars) blood. Gosselaar had the look (and he still does), the appeal, and the good sense to have taken on such a role. He could have really worked wonders with the character, and it's a shame it wasn't a property sought.
