Actor Tobey Maguire, who will star in the motion picture "Seabiscuit," about the famous racehorse, introduces the Horse of the Year Award at the 32nd Annual ECLIPSE Awards show, in this Jan. 27, 2003 photo, in Beverly Hills, Calif. Maguire has been yo-yo dieting lately, but it's work-related. He bulked up to star as the webslinging crimefighter in last year's ``Spider-Man,'' then trimmed down to play a jockey in the upcoming ``Seabiscuit,'' then had to get buff again for next summer's ``Spider-Man 2.'' ``Coming off of 'Seabiscuit' and going into 'Spider-Man,' it's different physically,'' the 27-year-old actor told MTV News.
