10 Actors Who Appeared In Star Trek AND Battlestar Galactica

10. Sam Witwer

In 2024, Sam Witwer had three separate roles in Star Trek. In the fifth season of Star Trek: Lower Decks, he played both Legnog — the faking-it Klowahkan food critic with all the plumage — and Malor — the hapless but extremely helpful Klingon, brother of Ma'ah. Then, in the best of anniversary surprises, Witwer was James T. Kirk himself, under an eerily good digital mask of William Shatner for OTOY and the Roddenberry Archive's 765874: Unification.

Before all that, Witwer had been equally unrecognisable beneath another kind of prosthetic as a Xindi Arboreal in the Star Trek: Enterprise episode The Shipment. Un-masked, many would soon come to know the Illinois-born actor's face as Lieutenant Alex Quartararo on Battlestar Galactica.

'Crashdown,' Quartararo's call-sign, or 'Crash' if you were familiar, was an officer of the Colonial Fleet who previously served aboard the Battlestar Triton. After the Fall, he became Raptor ECO (Electronic Countermeasures Officer) on Galactica. We first met him in season one's debut episode 33. Crashdown would go on to play a key role in the Colonials' continued survival and provide a look at their past. To tell you more than that would be to tell you more than you'd want to know.
