"Bryce Dallas Howard, the actress best-known for playing Gwen Stacy in "Spider-Man 3" and for starring in the worst M. Night Shyamalan films, will join the cast of "Twilight" starting with the third film "Eclipse" (scheduled for release in 2010). 
She'll take on the role of Victoria, the nomadic vampire who is trying to kill Bella and whose role beefs up significantly in the third film.
Howard is something of Hollywood royalty, as her father, Ron Howard, has been in the business for decades. He broke in as a child star on "The Andy Griffith Show", graduated to a role on "Happy Days" and has since become one of the most prolific and varied directors in film, creating modern classics like "Apollo 13", "Willow" and "Cinderella Man". (He is also responsible for "The Da Vinci Code", but it's hard to hold that against him considering he brought "Arrested Development" to television). 
But though Ron's contribution to American pop culture is great, his best recent work has been in a cameo in the video for Jamie Foxx's "Blame It" where he is seen rolling with Jake Gyllenhaal, Forest Whitaker and Samuel L. Jackson at a club. It's hard to believe that Ron is much of a club guy, but he makes the appearance work if only because his look could easily be described as anti-hip-hop. Still, he looks more at home toasting champagne with those ladies than Gyllenhaal does".Source: newsroom.mtv.com
