8 More Actors Who Look Exactly Like The Characters They Played

While Ana de Armas definitely did a fantastic job of portraying Marilyn Monroe during last year's Blonde, it's still pretty difficult to top the exceptional Michelle Williams' work as the one-of-a-kind big-screen star in 2011's My Week with Marilyn.

At a glance, Williams could easily pass for a Monroe lookalike, with the actor looking almost spookily like Norma Jeane when sporting her hairstyle and signature mole.

But what really helped take her performance in the well-received biographical drama up a level was the star's ability to perfectly capture the way Monroe would breeze her way through a conversation.

Williams also went as far as to bleach her hair blonde and put on weight to play the part.

And while the actor herself initially set out to simply channel her essence (via THR) when playing the icon, all of the months of research and her unquestionable dedication to playing the many faces of Norma Jeane eventually resulted in Williams transforming into a captivating Monroe doppelgänger.
