Many crew members appeared in "Wormhole X-Treme!", the 100th episode of Stargate SG-1. The director of a Wormhole X-Treme! episode, played by Peter DeLuise, was the director of this Stargate SG-1 episode. A Wormhole X-Treme! writer is played by Robert C. Cooper, a Stargate SG-1 writer and executive producer. Further cameos include Joseph Mallozzi, producer N. John Smith, and Stargate SG-1 writer Ron Wilkerson as Wormhole X-Treme! crew members; Stargate SG-1 property master David Sinclair as the Wormhole X-Treme! assistant director; make-up artist Jan Newman as a make-up artist; director Andy Mikita and producer John Lenic as the characters being beaten by Col. Danning; Stargate SG-1 director Martin Wood as an NID agent; and several more. The two executives who commented on how unrealistic Lloyd's spacecraft looked are played by Stargate SG-1 executive producer Michael Greenburg and executive producer/co-creator Brad Wright. In "Proving Ground", Elisabeth Rosen appears as Lieutenant Jennifer Hailey, who originally appeared in the episode "Prodigy". Courtenay J. Stevens appears as Lieutenant Elliot, a role which he would reprise in the episodes "Summit" and "Last Stand". He would also later appear in the first season of Stargate Atlantis, playing the role of Keras in "Childhood's End." David Kopp appears as Lieutenant Grogan, who would return in Season Five episode "The Sentinel". Grace Park, famed for her appearance on the re-imagined Battlestar Galactica as Sharon Valerii, makes an appearance as Lieutenant Satterfield. "48 Hours" marks the first appearance of David Hewlett as Rodney McKay. He would recur in future Stargate SG-1 episodes and join the main cast of Stargate Atlantis. For "Summit", Martouf was originally meant to appear, having survived "Divide and Conquer." However, J. R. Bourne was unavailable for filming, which necessitated developing a new host for Lantash. Jonas Quinn makes his first appearance in "Meridian", and goes on to take Daniel Jackson's place on SG-1 throughout season six. Jackson does not appear in "Revelations". However, it is implied at the end that the breeze SG-1 feels is Daniel. Michael Shanks does appear as the voice of Thor. This is the last episode where Michael Shanks would be listed in the main cast until season seven. Teryl Rothery who portrayed Janet Fraiser does the voice of Heimdall. According to the episode audio commentary, Rothery performed her lines on-set to help give the actors a reference point. However, Richard Dean Anderson, Christopher Judge and Rothery could not keep a straight face as the eye line they were given was a blinking light in Rothery's chest. This episode ended the SG-1 tradition of ending the season with a cliffhanger until Season 9.
