OK, maybe not the most obvious Fantastic Femme, but Mary Lou Retton does have genre credits, even if it is as herself!
Genre credits include...
Scrooged (as herself playing Tiny Tim in a live tv production of A Christmas Carol)
Naked Gun 33 1/3 : the Final Insult (as herself)
Mary Lou's Flip Flop Shop (as herself)
Her own WebSite
