Jeffrey Combs (Penk) and J.G.
Hertzler (Hirogen hunter) both previously played recurring
characters on Star Trek: Deep Space Nine. Combs played Weyoun
and Brunt and Hertzler played General/Chancellor Martok.
Interestingly, this marks the first time that the two actors
have acted in a scene together. It is also the only appearance
in Star Trek: Voyager for either actor.
As with "Blink of an Eye", this
episode's title had to be changed shortly before shooting when
it was realized that it matched a TOS episode's: "Arena".
Many of the aliens seen in this
episode were background characters in Deep Space Nine.
The Pendari Champion was played by
pro wrestler The Rock, a tie-in between UPN shows Voyager and
WWF Smackdown! (now known as WWE Smackdown!). During the fight
between Seven and the champion, The Rock used "The Rock Bottom",
his pro wrestling finishing move. The Pendari Champion also did
"The People's Eyebrow," a typical Rock gesture.
The Rock was the first WWE
superstar to appear on Star Trek. The other two were Tommy
"Tiny" Lister, Jr. and The Big Show, who both guest-starred on
Star Trek: Enterprise.
The Tsunkatse costumes had some
real-life functionality. The gloves were powered by six AAA
batteries allowing the hand pads to light up. The shoes (made by
Nike) also had some light-up functionality.
This episode marks one of the rare
occasions where Torres is left in command of Voyager and the
only time she sits in the captain's chair. Torres was briefly
seen in command of the bridge during "The 37's" when all the
other senior officers were on the planet's surface.
