Diane Lane better make some room on her mantelpiece -- the actress is following in the footsteps of Oscar winners Halle Berry and Charlize Theron and de-glamming herself in the name of a dramatic role.

The 45-year-old star looked less than groovy as she shot scenes the HBO film "Cinema Verite" Aug. 24, wearing dark, lank, '70s-style hair, large tinted eyeglasses, a printed pointy-collared shirt, and a short white belted jacket.

Joining Lane as she strolled through New York City's Central Park was actor Thomas Dekker, who, with his luxurious locks and far-out leather jacket kinda looked prettier than his dowdy co-star.

In the film, Lane plays Pat Loud, matriarch of the clan chronicled in PBS's groundbreaking 1973 docu-series "An American Family," according to the Daily Mail.

The documentary, which paved the way for reality shows like "The Real World" and "Keeping Up With the Kardashians," followed the Santa Barbara, Calif., Loud family as they coped with issues like divorce and the coming out of son Lance, who is played by Dekker in "Cinema Verite."



Much like last year's HBO film "Grey Gardens" -- which earned Drew Barrymore a Golden Globe for her portrayal of the eccentrically attired Edith Bouvier Beale, aka "Little Edie" -- the new movie will tell the story of the making of the documentary.

With all these behind-the-documentary biopics becoming so popular, we wouldn't be surprised to turn on HBO thirty years from now and see Katie Holmes playing Anna Wintour in a dramatization of "The September Issue."
