In 2007, it was announced that Hertzler would play Harry Mudd in a forthcoming edition of Star Trek: New Voyages, which he would also direct.

In a special feature on the DS9 7th Season DVD set (disc 7), Hertzler remarks, "You know, the thing about Star Trek is they use more theater people, Shakespearean-trained (I've done a lot of Shakespeare – most of the Klingons have done a lot of Shakespeare) and that's something that Star Trek was unique. Is unique. They tend to go with people who can operate in a strangely heightened reality and somehow make it as close to reality as you can. That's sci-fi, you know, that's what you need."

Hertzler was interviewed for the DS9 documentary What We Left Behind.
