Teryl Rothery (Janet Fraiser) provides 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, Chris 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 broke the SG-1 tradition of ending the season half way through the episode, or an end of the season cliffhanger. Reception This episode was nominated for an Emmy in the category "Outstanding Special Visual Effects for a Series", and won a Gemini Award in the category "Best Visual Effects".
