10 Best Sci-Fi Film Comedies Of All Time

10. Back To The Future Part 3

The epic conclusion to the brilliant Sci-Fi trilogy still rates today as one of the greatest Comedy sequels of all time. Unlike many of the great trilogies, including The Godfather and Spiderman, this trilogy absolutely sticks the landing.

The transition to the Wild West allows for a new story to develop in exciting fashion, without getting bogged down revisiting the previous film's events like the second entry did. Robert Zemeckis once more realises the comic potential from the time travelling plot device, with Michael J. Fox's Marty McFly doing his best to keep his old pal Doc Brown alive in 1895, without getting himself killed in the process.

The key to the film's success is once more the outstanding acting, the Christopher Lloyd/Michael J. Fox combo working to perfection once more. From Fox's Clint Eastwood impersonations to Lloyd's 'drunken' rant while not actually consuming any alcohol, the acting has us cheering for our protagonists while chuckling with them all the way to their final tain adventure.

While Biff Tannen had always been a big bully in previous entries, his grandad proves to be the best antagonist of the trilogu. Thomas F. Wilson makes the transition to mass murdering 'Mad Dog' Tannen in grand style, bringing to life the best villainous tropes from the grand era of Westerns.

The inclusion of a love interest for Doc Brown is a great new angle, Mary Elizabeth Winstead's damsel in distress keeping the story fresh and allowing for a great sendoff for the beloved scientist.
