There are 87 different listings here for various movie / tv Cleopatras based on the historical figure.

Jennifer O'Dell started acting at the age of 8 and did a range of commercials, tv guest appearances and minor film roles until her early 20s.
Jennifer finally secured a starring role as the scantly-clad Veronica in the tv version of The Lost World playing a character not in the original novel or any prevous tv or film version! (And, IMHO, she was the best thing about the series, easily outshining the cheesy "special effects"!)
Since the show's never-resolved cliffhanger demise, she's been doing guest shots on everything from comedies like Two and a Half Men to genre shows as well as featured roles in a variety of movies, usually scantly-clad (not that I'm complaining).

Trivia: She's actually a brunette, but most of her roles (including Veronica) show her as blonde.
