Supermodel doc 'About Face' to premiere on HBO

HBO documentary "About Face: Supermodels Then & Now" premieres tonight.

The documentary, filmed by Timothy Greenfield-Sanders, will feature interviews from Supermodels Christie Brinkley, Beverly Johnson, and Bethann Hardison.

"People go into the film thinking, 'Oh, it's going to be some kind of fluffy film about the fashion world,' and then they leave it overwhelmed," Greenfield-Sanders told CNN.

The film touches on the fashion world's most controversial issues like, aging, racism, drugs, plastic surgery, and more.

You can catch it tonight at 9 p.m ET on HBO.
