Film Brain

Film Brain is the character created by Mathew Buck for the review show Bad Movie Beatdown, a show dedicated to reviewing exceptionally bad mainstream movies. Buck produces the show under the production title New Dawn Productions (though later episodes of the show have dropped that title card) for thatguywiththeglasses.com.

Buck started with TGWTG as the moderator for the site's forums, while writing and posting articles. In April 2009, he started Bad Movie Beatdown, stating that his show would be different from The Nostalgia Critic in that his show would involve more recent films that would go past the Critic's year 2000 cutoff date. His first review was of the Eddie Murphy film Pluto Nash.

Along with his strong British accent (he is a resident of Swindon, England), Film Brain's commentary style is known for being more deadpan and dry than many other online reviewers. He also rarely if ever uses profanity, similar to Linkara; in early episodes, he might occasionally use profanity but bleep it out in editing. As the show has progressed he has gotten more comfortable in showing intensity on camera and using harsher swear words without bleeping.

FIlm Brain is one of the few reviewer characters who regularly states his real name in his videos, ending each review with "I'm Mathew Buck, beating down bad movies everywhere!"

Film Brain has grown to be one of the more popular reviewers on TGWTG, but it has also resulted in his detractors. There have naturally been those who find it hard to get behind his thick British accent during the reviews. Much of the disdain that exists among the detractors, however, stems from his decision to make the cult film Equilibrium one of his first reviews; the site's administrators had to post multiple calls to ask commenters to be civil in expressing their opinions due to extreme opposition to Mathew's views on the film. To his credit, FB would poke fun at himself for the review in later installments and admit that he was still learning about video production at the time he made it, stating he would have likely done a better job nowadays although he still stands by his opinion of the movie.

He also got criticism for adding an additional character called "Lord Hebebe"; a persona played by Christopher Barnhard wearing gag glasses and a brightly colored wig while serving as FB's researcher for the show. Many people did not seem to find the character entertaining. Lord Hebebe has barely appeared on the show since its second season.

Buck eventually started taking part in other projects like the site's major crossover anniversary specials, starting with "Kickassia". In fact, traveling to take part in that project was his first trip ever to the United States. For the movies, Film Brain has been much more hyperactive and gleeful than the dry character portrayed on his own show; Buck has stated the portrayal in the movies is admittedly closer to his own persona.
