It seems most Trek actors don't do other major work post-Trek (,i.e. being in a series). The exceptions are most of the Original Series, many of TNG, and Alexander Siddig from DS9.
Is it because Trek pays well, and they don't need to work again? or that Trek has burnt them out, and they don't feel a need to work again? Is it also based on how popular a series is? TOS and TNG are the most ingrained into popular culture, hence why Shatner and Sir Patrick Stewart are world famous. And Alexander Siddig (whilst a good actor) lends well due to his Arab background (I feel it is a factor since most of his roles feature him playing an Arab).
