IMDb: Rachel McAdams
Wikipedia Intro: Rachel Anne McAdams (born November 17, 1978) is a Canadian actress. Her films include Mean Girls and The Notebook (both 2004), as well as Wedding Crashers and Red Eye (both 2005). McAdams played the title role in the film The Hot Chick alongside Rob Schneider, but her career really progressed when she starred as Regina George, the queen bee in 2004's Mean Girls. McAdams was told to partly model the character of Regina George after Alec Baldwin's performance in Glengarry Glen Ross (1992). She was much older than the character she played. McAdams had previously appeared in the Canadian television series Slings and Arrows, co-starring Paul Gross. She played a main role in the first season, but due to her rising stardom was written out of the second season, appearing in only the first episode. She followed Mean Girls with the film adaptation of Nicholas Sparks' novel The Notebook, with Ryan Gosling, with whom she would later begin an off-screen romance.
