One
 of the best sequences of THE SKULL (1965) is the extended dream 
sequence.  Director Freddie Francis handles the transition from reality 
to fantasy so skillfully that the audience is not even aware of the fact
 that they are watching a dream. Sooner than rely on distortion filters,
 a la Roger Corman, Francis lulls the viewer into a state of blissful 
ignorance as the protagonist, Professor Christopher Maitland (Peter 
Cushing), drifts into unconsciousness and undergoes a strange and 
terrifying nightmare.
