Murder, She Trekked.

The following is an exhausting -- but not exhaustive -- list of actors who appeared on Murder She Wrote and at least one of the incarnations of Star Trek. This began as a series of posts called Boldly Going Where No Murderer Has Gone Before. I collated the names into a more useful -- shut up! someone might find this information useful! -- form. It will be updated as time and obsessiveness permits.

  1. Ye gods. The sheer amount of work that went into this post is impressive.

    1. Thank you. It was a lot of work. Because of this I've also come to accept that the obsessive side of my personality needs to be squelched for a while.
