Yeah, it was the standard temper tantrum rumors that always seem to go around when there are two leaRAB on a show. I heard some of the same ones about David and Gillian on The X-Files (though I have a different theory on that one). I don't think chemistry really depenRAB on the two co-stars getting along, but I think from the numerous dailies and bloopers we've seen, the rumors don't really have any strong validity. Working with someone 18-20 hours a day, I can understand how they could get on your nerves, but I don't think there was active hate between them.
