I once started tallying up "Doctor Who numbers". They were sort of like Bacon numbers, except that instead of counting the number of links (via IMDB) to Kevin Bacon, they counted the number of shared actors and/or major production staff were shared between a series and Doctor Who. I used to have a bunch of lists, but on my PC at work it seems I only have a partial list, with just one franchise listed. "Highlander" nets a figure of 18 (if you include the movies, which lets you include such notables as Michael Jayston -- the Valeyard -- and the very famous costume designer James Acheson). I haven't tallied up anybody from the new Who series, though, and I'm missing all the lists I made for other shows.<br /><br />I think "Hitchhiker's Guide to the Galaxy" got the highest ranking of any that I looked at, which really isn't a surprise at all. <img src="/images/icons/tongue.gif" /> It was practically produced down the hall from Dr Who, and its very creator has a major Who link!<br /><br />Surprising shows with a strong Dr Who link include MacGyver. Did you know that MacGyver was created by the guy who invented the Daleks, Terry Nation? <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em> -- The Tenth Doctor, "Blink"</font></p> </div>
