An extended look at the first three regenerations of the Doctor (William Hartnell - Patrick Troughton - Tom Baker) which includes reactions to his new bodies and the selecting of each new wardrobe. This video is Part 1 in a series. This version of the theme music is performed by Orbital.
*This video was originally posted on Youtube as "Doctor Who Extended Regenerations" (posted under the user name 'Yusteles') but has since been blocked so I transferred it here. I could only save the version that was covered in annotations so I hope you don't mind the trivia track! Also, this video was made a few years ago when I only had Windows Movie Maker so please excuse the poor quality as well.
