When I first saw the movie Hotel for Dogs with my kids, I spotted the Shakespeare reference to the two dogs in love – they were named Romeo and Juliet, obviously.
Upon watching it on video with them, however, I noticed what had escaped me previously. The brother and sister dog are named Sebastian and Viola.
Anybody could have come up with the first one, but methinks one of the writers is something of a Shakespeare geek to have snuck that second one in there ;). If we assume in context of the movie that it was the young kids who were naming all these stray dogs, and they were the ones that came up with the Shakespeare references? All the better!
