This weekend was a celebration of all things Doctor Who for the 50th anniversary of the venerable British sci-fi series.

I really enjoyed “Day of the Doctor,” yesterday’s anniversary episode.

But if you haven’t seen it, I’ll urge you to watch “The Five(ish) Doctors,” a 30-minute film by Peter Davison, who played the fifth doctor.

In the clever and cameo-filled movie, Davison is joined by two other Doctor actors, Colin Baker and Sylvester McCoy, who scheme and plot to get into the anniversary episode.

These three actors display enormous good humor as they plot and bicker and connive to get into the historic episode.

It’s a funny Who-centric short film that’s also a great commentary on show biz.

Here’s the film.
