Dalek Invasion of Earth, Part 1

Jessica and Phillip begin their two-part series of exploring Daleks, the Doctor, and Peter Cushing. In this first installment, they examine the First Doctor Adventure "The Dalek Invasion of Earth" which served as the inspiration for the second Doctor Who film, starring Cushing as the Doctor. This six-part serial provides adventures for William Hartnell's Doctor, as well as Ian, Barbara, and Susan (who leaves the series at the end of this serial). What made this story good enough for a feature film?

In their look into the TARDIS library, the couple revisits "Dalek," the Ninth Doctor story that "re-introduced" the Skaro fiends to "nuWho." What makes a single Dalek so scary? Plenty, it turns out.

Which First Doctor adventure do you think would have made a great movie?
