Though he may never have hit megastar status, Robert Patrick has been a stalwart presence in Hollywood ever since his biggest role as the T-1000 in James Cameron's seminal "Terminator 2: Judgment Day." So definitive was his performance that Patrick has actually played the T-1000 outside of "T2" multiple times, despite the fact that his character was never officially brought back for any of the sequels.
But any fan of the actor will know that he's also had a consistent and actually pretty darn impressive run of work ever since that 1991 blockbuster. He also remains active today, most recently showing up in season 2 of Prime Video's "Reacher" series, where his primary antagonist was a clear homage to his role in Cameron's classic. Patrick also played a frankly horrible human being in season 1 of "Peacemaker," and could be seen in season 1 of the short-lived HBO series "Perry Mason."
In fact, TV has been where Patrick has really shone in recent years, as his film roles have mostly been in smaller, direct-to-VOD type action fare. But then, TV has always provided a good home for the actor, who actually helped kick off the "Stargate SG-1" spin-off "Stargate Atlantis" back in 2004 when he guest starred in the two-part pilot episode "Rising." Patrick played commander of the Atlantis expedition, Marshall Sumner, but didn't make it out of the second part of the pilot. Why wouldn't "Atlantis" want to keep such a dependable talent onboard? According to Patrick, he had other commitments.
