Season Three of the fantasy sitcom
3rd Rock from the Sun opens with another dilemma for the group of space aliens who have assumed the human form of the "Solomon" family for the purpose of gathering intelligence on the planet earth: It seems that group leader Dick Solomon (
John Lithgow) has been ordered to marry Janet (guest star
Roseanne), the niece of his superior back on his home planet, the Big Giant Head. Dick somehow manages to wriggle out of this because of his loyalty to his earthling sweetheart Mary Albright (
Jane Curtin)--a loyalty that unfortunately proves to be a one-way street when Mary (still unaware that Dick is an alien) breaks off their relationship, thus launching a recurring motif wherein both Dick and Mary would like to get back together, but are too stubborn and prideful to admit it. In another story strand, Janet's arrival on earth proves so unnerving to Officer Don (
Wayne Knight) that he immediately begins suspecting that an alien invasion is imminent--never dreaming that his own girlfriend Sally Solomon (Kristen Johnson) is herself Not Of This World. As for the other two members of the alien team, scientist Tommy Solomon (
Joseph Gordon-Levitt)--a middle-ager trapped in the body of a human teenager--yearns to date someone closer to his "real" age (such as Mary) and later "retires" to a nursing home, while doltish crew member Harry Solomon (
French Stewart) undergoes an offbeat reunion with his former pet, who has likewise taken on human form. Midway through the third season the Solomons must themselves fend off extraterrestrials when the earth is invaded by Venusians disguised as buxom females (including models
Angie Everhart and
Cindy Crawford) in the two-part episode "36!24!36 Dick". And in a later two-parter, "Just Your Average Dick",
John Cleese does a screamingly funny turn as nutty professor Dr. Liam Neesam, who turns out to be an alien-in-disguise himself--not to mention a worthy adversary for Dick in the war to win Mary's hand and heart. The traditional season-ending cliffhanger finds a romantic "kiss and make up" dinner being ruined when the volatile former boyfriend of Harry's human girlfriend Vicki (
Jan Hooks) bursts in and kidnaps Harry--just in time for the Solomons to miss an extremely vital transmission from their home-planet superior officer, The Big Giant Head. ~ Hal Erickson, All Movie Guide
