Sumo Bruno (originally titled Sumo Bruno – Dein schwerster Gegner bist du selbst) is a 2000 German comedy drama film directed by Lenard Fritz Krawinkel and starring Hakan Orbeyi, Oliver Korittke, Julia Richter, Martin Seifert, Thomas Drechsel, Tim Wilde and Martin Semmelrogge.

Bruno (Hakan Orbeyi) is a lonely, unhappy, 400-pound man that has recently lost his railroad job on his 30th birthday, and was informed by a tax-collecting bailiff (Hans-Jochen Röhrig) that he's in danger of losing his home due to very late payments.

Later that night, Kalle talks Bruno into a double-date with Gina (Esther Esche) and Bärbel (Sandra Steffi), and going to the local discothèque, Lucky's Temple of Dance.

Feeling out of place, Bruno goes to the men's restroom, where he meets the beautiful Anna (Julia Richter), who's hiding from her boneheaded boyfriend, Lucky (Tim Wilde), the owner of the club.

The next morning, due to circumstances involving a ten year old, chubby, bullied boy named Timo (Thomas Drechsel), Bruno finally decides to enter the sumo championship.

Despite the fact that complications have arisen, like clashes with Akashi, money problems and obvious attraction for Anna, Bruno does himself proud with qualifying in the preliminary and will represent Germany as one of two German participants along with menacing rival R.F.

Kalle's machinations to boost his very large friend's popularity and make some money ends-up backfiring badly, with the end result seriously damaging Bruno's confidence which negatively impacts his blossoming relationship with Anna and Timo.

Lifting by the audience rapturous applause to such a fantastic effort, Bruno graciously bows to the champion, and walks away from the arena with his head held high, knowing that despite the outcome, he's truly a winner in his heart, mind and soul.

Director Krawinkel said about Sumo Bruno, that he "wanted to tell the story of an overweight person who gets going again, as a representative of all who know what it feels like when life has temporarily come to a halt.

It's a sport the first rule of which says: The fatter, the better..." Krawinkel comments on casting: "For the main role of Sumo Bruno, I was looking for an overweight actor with an erotic appeal.

The opening and ending song "What I Wish to Be" (lyrics by Deborah Wargon), was sung by the Children's and Youth Choir of the Theaters of the City Heidelberg, headed by Heike Kiefner.
