☐ Too Tough For SNL Hosts

Could somebody please explain to me why almost every Saturday Night Live host is always looking off set when they perform in a sketch? It’s horribly obvious they are looking at the cue cards, and sometimes, they don’t look anywhere BUT the cue cards.

They are supposed to be professional actors who have to memorise lines, rehearse, and so on just the same as the SNL cast do. Why then do they all constantly and continuously read the cue cards? Do they not remember ANY of their lines? Is it that they are unable to learn them in only a week? Did they not go to rehearsals?

I don’t understand why they are so dependant on the cue cards when they are doing exactly what they are trained for: acting. Perhaps the rigors of a weekly sketch comedy show are tougher than those of a long movie production. If this is the case, then going in the other direction (sketch comedy to movies) should be a piece of cake.
