3rd Rock From The Sun S5

John Lithgow has had quite an extraordinarily varied career over the last forty years, on stage and screen. He had major roles in Brian DePalma's thrilling Blow Out, Twilight Zone: The Movie (playing the same role as fellow 3rd Rock actor William Shatner), Terms of Endearment, Footloose, Harry and the Hendersons, Memphis Belle, Raising Cain, Cliffhanger, and many more.

The leggy, busty, brassy blonde bombshell of the group, Sally Solomon is actually only female because her original (asexual) alien form lost a bet! Nevertheless, while the female of the human species is understandably even tougher to work out than the male, she soon starts to revel in it.

In a show about aliens in human form, struggling to get used to our bizarre Earth ways, Harry Solomon is unquestionably the one that struggles more than any other.

Artistic or autistic? It's a fine line...

So much more than just a 'straight man' to the wacky alien antics, she is one of Dick's prime sources of information about humanity, whether she realises it or not.
