Zak Penn and Werner Herzog perform the DVD commentary while still in character, trading insults frequently, scolding each other and referring to a fake legal agreement that presumably would have been reached after the events of the film take place. Their argument gets so heated that Herzog 'leaves' and the commentary stops and then restarts, this time hosted by Penn and producer Jana Augsberger.
Playboy model and actress Kitana Baker said she enjoyed making this film, but it was weird not having to strip her clothes off like in all her other roles. During the scene where she's wearing a bikini on the boat, Baker, who admitted in interviews that she enjoys being naked in front of other people, told director Zak Penn she'd do it topless or even fully nude to "help video sales." He declined, which Baker said really seemed to upset the rest of the crew.
When asked by an audience member after a viewing at the Edinburgh Film Festival 2004, whether any Nessies were harmed during the making of the film, director Zak Penn indicated that he could not guarantee that they were not.
