A film's foundation is (inarguably) its writing; thus, I've always wondered why actors, and even directors, often get more notoriety than writers.
Thus, I wasn't completely surprised to learn that Ridley Scott, the director of Alien, Blade Runner and Gladiator - to name a few, reportedly agreed with me when he concluded:
"[...] writing is everything. Everything else is dressing. Sorry, actors."
