It's a mawkish, obvious family comedy, but Dwayne (The Rock) Johnson scored a No. 1 hit with The Game Plan. Why? Pairing a macho star with a cute kid or kids often equals box office gold. Before The Rock pulled on ballet tights in Plan, there was Arnold Schwarzenegger in Kindergarten Cop (1990) and Vin Diesel as a Navy SEAL turned babysitter in The Pacifier. The formula isn't foolproof; though Hulk Hogan donned a pink tutu, few bothered to catch the ex-pro wrestler (The Rock of his era) in the dopey Mr. Nanny (1993).
