I already have five of the Doctors from Character Options, and the three Dapol Doctors. I've just ordered the First Doctor set as well. Before I started roleplaying, I had already begun collecting action figures of Doctor Who and staging scenes with them for photographing, as many people do on Flickr. The selection of action figures from Character Options is very impressive, with many different variants. As is the series of Torchwood figures made by SciFiCollector, though that series has just eight figures so far (also with variations on the Jack action figure).
Seen here are Tosh, Ianto, Jack, Gwen, and John. Other figures in the range are the Cyberwoman, Blowfish and Weevil. This Jack is from the Doctor Who "Utopia" series. There is also a Torchwood version and "The Empty Child" version. I also have these in my collection. The Doctor Who and Torchwood figures are in the same scale, so they can be placed together. They are a great way to display the world of Doctor Who and collect items related to the show.
