Shooting on Justin Lin’s “Fast and Furious” is already well underway, but new castmembers are still being added. First up is actress Liza Lapira, who IMDB.com has listed as playing an FBI agent name Sophie Trinh, a character that will be giving Paul Walker’s Brian O’Conner a hand tracking down some wanted felons. The other casting is rapper Lil Wayne, who is currently in negotiations to join the fourth installment in the popular car franchise. News about Lil Wayne comes from Contact Music, who has no word on who Lil Wayne would play, but casting a well-known hip-hop artist would seem to jive with the previous “Fast and Furious” films. Ludacris filled the role in “2 Fast 2 Furious”, and “Lil Bow Wow” did likewise in the previous installment, “Tokyo Drift”, which was also directed by Justin Lin. Fans of TV, especially CBS’ Navy NCIS, will probably recall Liza Lapira (pictured, below) as Special Agent Michelle Lee on the show. The Filipino actress was also recently in the surprise hit “21″, about MIT students who use their skills to break Vegas casinos. “Fast and Furious” (aka “The Fast and Furious 4″) is due out in 2009.
