Those Stargate actors

Watching Eureka on Tuesday evening I noted several familiar faces sci fi faces on the show. The sherrif was a cupcake eating goa'uld on SG-1; the colonel was a Russian colonel on SG-1; and I was really amused to have the main character - the marshall - have the name Jack Carter.

Coincidence?

I think not.

Tonight watching SG-1 the doctor they brought from earth to determine what was wrong with everyone was another familiar actor. Just got it . . . he was in one of my all time favorite episodes, Window of Opportunity - or GROUNDHOG DAY! He played the guy on the planet responsible for the time loop Teal'c and O'Neill were stuck in (ending a sentence with a preposition - shame).
