Willow's guest appearance here makes her the 2nd most prolific character in the Buffyverse, giving her 147 appearances (144 on Buffy the Vampire Slayer (1997) and 3 on Angel (1999)). Angel is the most (110 appearances on his own show and 57 on Buffy) and Buffy the third (144 on her own show and 2 guest slots on Angel).
Alyson Hannigan had to shoot all her scenes in two days because she wasn't only working on the final season of Buffy the Vampire Slayer (1997) at the same time, but also on American Wedding (2003)
Alyson Hannigan was excited to work with her fiancé, Alexis Denisof, whom she met while the two were on Buffy the Vampire Slayer (1997). Denisof was also excited. "I feel like it's a play day. I have to keep reminding myself that I'm at work," he said. "My girl is here... really all I want to do is run over and give her a hug."
Parting Gifts (1999) saw Angel Investigations in its smallest form with only Angel and Cordelia left and Wes not yet formally part of the team. 'Orpheus' sees it at its maximum strength with Angel, Cordelia, Wes, Fred, Gunn, Lorne and Connor with Faith and Willow as temporary members.
With this episode, the "cross-over embargo" between The WB and UPN is lifted, allowing characters from Buffy the Vampire Slayer (1997) to cross-over to Angel, and vice-versa. The last cross-over was seen in There's No Place Like Plrtz Glrb (2001), again with Willow coming to see Angel Investigations, but to inform them on Buffy Summers' death in The Gift (2001). This also marks the final appearance of Willow and Faith on the show.
Adrienne Wilkinson: voice-actress/model, best known for roles in Star Wars Video Games, appears as a flapper.
