10 Movie Superheroes Ruined By Terrible CGI

Whether it's being used to cover up an unwanted moustache or create an entire character from scratch, dodgy CGI is a filmmaker's bane. Ropey digital effects have the potential to shatter audience immersion and turn a movie into a laughing stock.

Many Hollywood blockbusters have been shot in the foot by their own FX department and the problem isn't always a lack of budget. Indeed, some of the ugliest CG abominations ever created have crawled out of the biggest studios in the business.

This issue is particularly prevalent where superhero movies are concerned, as CGI is often essential to convince the audience that a man really can fly, or run faster than the speed of light, or even swing across New York like an oversized arachnid.

When the film industry's special effects gurus play their cards right, the illusion can be seamless and the punters leave the theatre filled with a sense of awe. But when they get it wrong, the whole thing collapses like a house of cards... and that isn't a reference to Kevin Spacey's career, in case you were wondering.

Justice League is easily one of the most disappointing superhero movies ever made, and not just because of its underwhelming box office takings. The movie thrust several of the greatest comic book characters ever conceived into the mix together, so anything less than spectacular was always going to be considered a failure.

Zack Snyder's team-up showcase fell far short of its potential in virtually every way. It was plagued by all kinds of issues from the moment it entered pre-production, so the last thing it needed was the now-infamous Henry Cavill moustache saga.

The star had grown facial hair for his role in Mission: Impossible - Fallout, and when Justice League reshoots called for him to be clean-shaven again, Paramount Pictures saw an opportunity to make things difficult for Warner Bros and said no.

Warner's solution was to give Superman a digital shave, which meant covering up the lower portion of the actor's face with CGI and superimposing Cavill's mouth on top of the whole thing. The results, which stood out jarringly in the film's opening sequence, made it look like he had applied too much Vaseline to his lips.

One scene in, and Justice League did a better job of killing Superman than Lex Luthor and Doomsday managed in the previous film.
