<b>Brad Pitt</b>
Brad tends to look steamy in every role he plays. But in 2008's "The Curious Case of Benjamin Button" he played a guy role who started off as an old man and then grew younger.
It's no wonder the movie took home Oscars for art direction, visual effects and makeup.

<b>David Bowie</b>
The singer didn't quite look like himself in 1983's "The Hunger."
He actually looks much younger now than they made him look almost 20 years ago.

<b>Melissa Leo</b>
If you didn't know who Melissa Leo was before "The Fighter," you'd never know that it was just really great makeup that made the 50-year-old actress look way older.
She took home both the Golden Globe and Academy Award for supporting actress for her portrayal of Alice Ward.

<b>Dustin Hoffman</b>
The now 74-year-old was made to look like this in 1970 for "Little Big Man."

<b>Drew Barrymore</b>
Drew aged quite nicely in "Riding in Cars with Boys" (2001). It's amazing what some dark lipstick, pale skin and a mommy haircut can do to a person.

<b>Robin Williams</b>
Mr. Williams not only played an old person - he played an old <i>woman</i> in "Mrs. Doubtfire."
It took a fat suit and lots and lots of makeup, but he was quite believable as an old lady.

<b>Cate Blanchett</b>
The English actress is a really pretty woman, but when she played the harsh looking Queen Elizabeth in 1998, they made her look old and stiff.
The 42-year-old was nominated for an Oscar for her role in "Elizabeth."

<b>Ken Watanabe</b>
The Japanese actor plays the aging wealthy business man, Mr. Saito in "Inception" (2010).
(Warner Bros.)
<b>Gloria Stuart</b>
Gloria was not exactly a young woman when she played the part of 100-year-old Rose in 1997's "Titanic."
She was 87 at the time, and she still needed a team of makeup artists to make her look like a centenarian.

<b>Anthony Hopkins</b>
Sir Anthony Hopkins played Colonel William Ludlow in the cult hit "Legends of the Fall" in 1994.
He starts off as a middle-aged man and audiences get to see him transform into a limping old man after he suffers from a stroke.

<b>Martin Lawrence</b>
This comedian will do anything for laughs - even dress up like an old fat woman again and again.
Now that's dedication!
Martin has starred as Big Mama three times and the fourth "Big Mama's House" movie is due out in 2012.
Move over, Robin Williams.
