sci fi linkathon

For those who love actors, and sci fi (and sci fi actors), a tribute-a-thon dedicated to links in the chain...
-FORBIDDEN PLANET, 1956
This classic starring walter pidgeon and leslie nielsen, is where modern sci fi was born.
-STAR TREK "By Any Other Name", 1968
FORBIDDEN PLANET's doc (warren stevens) guest stars as captain of a hostile, super-advanced (but emotionally green) alien crew.
-STAR TREK (animated) "The Magicks of Megas-Tu", 1973
Who's that voice of powerful alien asmodeus? Ed bishop, star of classic brit sci fi UFO. Control yourself, fanboys (fangirls, feel no such restraint).
-THE STARLOST "The Return of Oro", 1973
One of the better episodes of a second-rate (okay, maybe third-rate) show, with a fine guest appearance by TREK's walter koenig.
-THE SIX MILLION DOLLAR MAN "Sharks", 1977
A sci fi swirl, as BUCK ROGERS' pamela hensley stars, with supporting turns by marc alaimo (DEEP SPACE NINE) and john de lancie (STAR TREK: THE NEXT GENERATION). The three most resonant non-regular sci fi recurring stars ever?
-JASON OF STAR COMMAND "Escape From Dragos", 1978
Throughout the first season, TREK's james doohan played canarvin, the commander with a heart of gold.
-BUCK ROGERS IN THE 25th CENTURY "A Dream of Jennifer", 1980
BATTLESTAR GALACTICA'S anne lockhart stars as a woman surgically altered to look like buck's loooong-lost love.
-BUCK ROGERS IN THE 25th CENTURY "Journey to Oasis", 1981
Okay, i'm breaking my own unwritten rule by having two episodes from the same series...but season 2 BUCK was so radically altered, it qualifies as a different show. This episode, one of the few worth watching, features a nuanced performance by mark lenard (TREK's sarek and PLANET OF THE APES' urko).
-STAR TREK: NEXT GENERATION "The Perfect Mate", 1992
With a romantic almost-triangle between picard, riker, and famke janssen (X-MEN 1-?), this episode also stars the sublime tim o'connor (BUCK ROGERS).
-SEAQUEST 2032 "Dream Weaver", 1995
Mark hamill (THE EMPIRE STRIKES BACK, JAY AND SILENT BOB STRIKE BACK) plays a blind genius, in a rich role - and acquits himself beautifully.
-TEKWAR "Chill Factor", 1995
STAR TREK's past and future collide, as DEEP SPACE NINE's nicole de boer takes a turn on this shatnervaganza (alas, this one's a "credit only" no-show for the man himself).
-STAR TREK: DEEP SPACE NINE "The Siege of AR-558", 1998
Perhaps as karmic reward for all those abysmal years of LOST IN SPACE (danger, will robinson!), bill mumy shows more one-off chemistry with nicole de boer than worf and bashir manage in an entire season.
-STARGATE: SG1 "The Other Side", 2000
Rene auberjonois (DEEP SPACE NINE) exquisitely plays the morally-compromised leader of an alien nation.
-ENTERPRISE "Detained", 2002
Dean stockwell (GALACTICA '04) leaps in for a QUANTUM reunion with mr. bakula, playing a concentration camp commandant.
-BATTLESTAR GALACTICA "Pegasus" (extended version), 2005
Actions and consequences, roads not taken...as much as one might bemoan michelle forbes' (STAR TREK: THE NEXT GENERATION) turning down a role on DS9, had she not done so, there's a fair chance the BSG producers wouldn't have tapped her for this prominent (and fantastic) turn.
-STARGATE: ATLANTIS "Michael", 2006
Connor trineer (ENTERPRISE) plays a devastatingly-abused alien who has been genetically-modified, with his memory erased.
