I think Roy Thinnes' role as "David Vincent" was unsurpassed; it is awfully difficult to appraise one's acting ability when the role they play has never, ever been played before--By anyone! I mean, Acting is an art of "role" playing-Mimicking- How does one confront such a disturbing revelation, as discovering
that Alien beings have infiltrated the earth, especially, when they look exactly(almost)as we do? His bewildered look, and keen reactions--and sometimes, non-reactions, were the hallmark of his craft- I think he was underestimated as an actor- His "down-to-earth" behavior is perhaps his saving grace.
Maybe it is a blessing in disguise- Actors today are wrapped up in their own self-certifying egos; and their idiot pride usually accellerates their status of, "Who was that?" after only a few years of practice. Roy, on the other hand, is impossible to forget- Ask anyone who is between the ages of 45 and 60, today if they know who Roy Thinnes is--or "DAVID VINCENT"--and I bet almost everyone will say,
"THE INVADERS"! The Show itself had promise- Perhaps, if I were to rewrite it, I would have opted for a more Soap-Opera, serial "hook" to follow a sequence- The Aliens seemed to have no plan- but, for the Obvious-Take over the world- Some episodes were comical! Donald Davis played a funny kind of Alien-- and, most had no sense of Humor-but, even some of the Women Aliens were too weird to be true. Their gadgets were cool. Spinning Crystal hypno-beams to extract info for interrogation was cool; and the "Death-Disc" was sinister, to say the least- The Ray Guns were clumsy the first season; new model in '68- The Aliens'willingness to commit suicide, unquestionably, was also odd. The Aliens also seemed to be good fighters, in a fist-fight; but also, died easily when wounded or shot- Roy Thinnes is from Chicago--and his accent came through--! It was cool- and here is a kicker--I am related to him! My mother's family is "THINNES" from Wisconsin; then Illinois--and yes--it is the same Family, originally from Luxembourg! I hope only one day to meet him, and introduce him to my son, Dominic- He is a Fan of "The Invaders"! as am I! Try to find these on Video--they are worth it- Nothing Gross, or Evil--just good, wholesome science fiction, at it's best- FrancoDomenico Lisanti
