One Million Years Before Raquel
After the opening introduction, where have the travellers landed? It's interesting to note the reactions of all four when the scanner reveals the outside view. Barbara accepts whilst Ian still believes it's an illusion. We get an iconic moment when Ian says "Doctor Foreman", to which the Doctor replies "Doctor Who?" And then another iconic moment, the first time the TARDIS doors opens and we see that they're somewhere else. It's a key scene, and director Hussein wisely chooses to shoot it from the rear of the characters, straight through the doors.
