Tim McGraw is one very busy guy. He's a father of three, husband to a fellow star and has an on-fire country career of his own -- and while that may sound like more than enough work for one person, he doesn't think so. Now, the 'Southern Girl' hitmaker is working on another movie.

McGraw will begin shooting next month, and admits that his future looks packed to the brim. "It's gonna be a busy winter," he tells ABC News. Although he's remained mum on what movie he's acting in, the superstar adds, "I don't know if it's a surprising role, but it's gonna be a great film."

Nashville Gab asserts that the country favorite may be starring in 'Five Good Years,' a movie about a young Kentucky coal miner forced into boxing ring to save his critically ill mother, which is rumored to star Melanie Griffith. However, since the film began shooting in 2010, it remains unclear if McGraw will grace the set of that movie, or be in something completely different.

Either way, country fans will be excited to once again catch McGraw on the big screen as they did with his previous films 'The Blind Side' and 'Country Strong.'

McGraw has also mentioned that once his schedule frees up, he'd be interested in acting on Broadway or on a TV show. The problem is, with his popularity at an all-time high, his schedule always seems full. For now, fans can be on the lookout for McGraw in a future film -- and elsewhere, once the timing is right.
