Eight years ago, Rachel McAdams hit Hollywood's map in teary, romantic drama "The Notebook." Since then, she has broadened her range of work to include laugh-out-loud comedies such as "Wedding Crashers," adventure films like "Sherlock Holmes" and recently, the Woody Allen movie "Midnight in Paris." But the Canadian actress has returned to her romantic roots with new drama "The Vow," due in theaters on Friday.
