I always found Snape/Rickman to be boring. Its not a hard role to play, and he gets very little screen time. Hans Gruber was much more interesting to watch. Snape? Meh.
Now I'm stuck wondering what the movie would be like if they just transplanted in Hans Gruber as one of Harry Potter's professors.
I bet the finale of the final movie would be bitchin'.
Final scene:
Harry stands alone atop the ruined roof of Hogwarts. He is beaten, bloody, covered in ash, and his clothes are in tatters.
He stands before Snape, who has cast off his robe in favor of a well-pressed suit.
He looks much less pale, and is sporting a well-groomed beard.
Snape adjusts his tie, an air of cold arrogance flows off of him as he turns to face Potter.
Snape: You yet live? You are much hardier than I thought, Mr. Potter. More so than your friends at any rate.
Harry: Damn you, Snape! It was all a lie! The return of Voldemort, the wizards' war. It was all just a diversion so you could get into the Ministry's treasury!
Snape: Ingenious wasn't it?
Harry: All this! (Harry gestures to the ruins of his school, the gouts of spellfire flickering amongst rising sorcerous thunderheads that rumble in the cyclonic skies above) All your pretension to be a great wizard, and you're nothing but a thief.
Snape (His cold veneer flashes with anger): I am an
exceptional thief! And I have tired of over a decade of your petulant teenage angst.
I will do to you what I did to your father and framed that fool Voldemort for so long ago.
Harry screams with rage and points his wand at Snape.
With a flick of the wrist, Snape sends Harry's wand skittering away.
Snape: (Snape smiles) Any last words before I cast you into the Abyss? What was it you said, Yippy...Kay...Yay?
Harry (voice deeper, brusque): Yippy Kay Deus Ex Machina Motherfucker!
Harry's form changes, he's taller, balder, and grizzled. He reaches behind, and draws forth a wand he had affixed to his back with holiday ribbon.
With a thunderous blast, the wand sends a bolt of light into Snape, who plummets to his doom, impaled upon the spires of the school.
John McClane: That's
two movies that's worked in, asshole!
Fade to black: cue rockin' guitar playing the American National Anthem.
