Standing out from the pop princess crowd dominated by blue-eyed blondes thanks to her confident demeanor and deeper voice as well as her look, Mumba became a fixture on MTV with her debut single "Gotta Tell You" and ranked a club hit with her follow up "Baby Come On Over". She then segued to the big screen in "The Time Machine" (2002), a Steven Spielberg-produced retelling of the H.G. Wells classic, directed by Wells' great-grandson Simon Wells (with an uncredited assist from Gore Verbinski). Mumba played Eloi, the ethereal futuristic creature who speaks an unknown language in a role devoid of any of the singing and dancing known to pad many a pop singer's feature work. The filmmakers were so impressed with Mumba's performance that she was called back to shoot additional footage, placing the character in more scenes and inserting her in the trailer, quite unlike the editing out many are subject to in their first feature outing.
