Worst action actor ever, no.
Shaq in Steel
Hulk Hogan - everything
George Cloony in batman
William Shatner - have you seen his fight scenes?
Hayden Christensen - Shitty as hell.
Jean Cluade Van Damm - everything especially street fighter
Sorry Prof too much competition for worst. They might not be total "action" actors but they made action movies far worse.
