His ease on camera didn't go unnoticed by the industry, which was no doubt searching for projects to attract the good-looking hot property. John Singleton's "Baby Boy" (2000) won out. A gritty drama starring Gibson as the titular immature young player with two children by two different women, "Baby Boy" would challenge the performer to rise to the formidable task of carrying the lead in a film on his first time out. With his sophomore album "2000 Watts" climbing the charts in 2001, Gibson cut a track with "Baby Boy" co-star Snoop Dogg, who collaborated on the soundtrack's lead off single "I'm Just a Baby Boy". Determined to keep music and his community service projects (Gibson founded the 2000 Watts Foundation, an organization created to better his hometown and provide opportunities to its young citizens) at the fore, Gibson would likely not be discouraged if his performance in "Baby Boy" led to the end of his acting career. If instead he lived up to the production's high expectations, this triple threat could prove an unstoppable force in entertainment.

In 2003 Singleton again tapped Gibson to star opposite Paul Walker in "2 Fast, 2 Furious," the sequel to "The Fast and the Furious" (without the first film's breakout star Vin Diesel or original helmer Rob Cohen). After a supporting turn in the military action remake "Flight of the Phoenix" (2004), Gibson reteamed with Singelton again to play one of four troubed foster brothers seeking to avenge the mysterious murder of their adoptive mother in the hard-edged, but sometimes implausible, revenge thriller "Four Brothers" (2005).
