Speaking to Blastr, Jaime Paglia explained that he is happy that Wil Wheaton and Jamie Kennedy will have guest roles this season.
Referring to Wheaton, he explained: "We had the potential for this particular character that we thought would just be perfect for him, [which] was designed to be potentially recurring. And the plan is hopefully that is going to happen in the back 10 episodes as well."
He added: "Jamie was a fan of the show and wanted to come over and play, so we found a role for him that we tailored a bit more in terms of the personality."
However, Paglia admitted that he has a list of people that he would love to have on the show.
"I've always wanted to have William Shatner play Carter's dad," he said. "I know that it's a long shot, probably, but Felicia Day is on our list. Eddie Olmos is on our list. Gosh, I know that - I know I have many, many more but those are at least a couple of the people that I would love to have... Ming Na is also on that list."
Eureka continues on Fridays at 9/8c on Syfy.
