3. Kilmer Goes Mad - The Island Of Dr Moreau
The legendary turkey is probably the best example of how not to make a movie: it is wayward, messy, and criminally stupid in places (most of them, in fact,) and while Val Kilmer's performance is not the worst thing about it by any means, noone emerged from it with too much credibility intact. Kilmer was a brilliant Batman - the best in the important opinion of Bob Kane - and though he was moved on for various reasons (mostly because he thought the villains were getting more screen time than himself - ironically a concern that might have saved some face for Batman & Robin if heeded) he could have gone on to be considered a great whose Batman career was cruelly cut short. Sadly, films like The Island Of Dr Moreau, which unthinkably followed the triple-headed success of Tombstone, Batman Forever (comparatively and personally) and Heat, made everyone question why exactly Kilmer had ever been so highly praised.
The Low Point The occasional flashes of brilliance - like Kilmer's mimickry of Marlon Brando - serve only to make the ludicrous low moments even worse.
