Picture of Southfork taken by Joe Siegler

One evening, I was watching Dallas on SOAPNet with my wife, and realized that there's quite a few actors who have been on Star Trek as well as Dallas.  I know this is nothing unique to either of these series, as many TV series have the same characters on them.   However, as I really like Dallas and Star Trek, I made the connection.  I do web sites for a living, and as any web designer will tell you (at least any bored one) you make a web page about things you like.   So here I am.

On the pages below I'll have links to pages of pictures for actors that have appeared on both shows.  If I have pictures, I'll definitely include them.   If you know of an actor that's not on the list, please let me know.  Also, if you have pictures of one of these that I don't have (or just better pictures than me), please email me, I'd love to use them.
