Pictured here on the set of "Did You Hear About the Morgans?," it appears that Sarah Jessica Parker's character is a bit more conservative than the star herself.

Aside from looking synthetic, I don't find this style to be the most flattering for SJP. The monotone shade and blunt bangs age her, and the matte finish makes her hair seem overly processed and dehydrated.

Seen here on the set of the new spy thriller, "Salt," Angelina Jolie plays a rogue CIA operative that dons a number of disguises— two of which have already surfaced (above).
