"I think David is one of the most talented actors around. He is just so incredibly versatile - he certainly hasn't type-cast himself into playing one particular role. Every one of the characters he plays is different and he allows his talents to span a wide range of genres. In each of his films he makes every role his own, but most importantly makes every character believable . In fact he is one of the very few actors who has the ability to completely draw you into a film and get you totally immersed in the characters, so much so that you care deeply what happens to them and actually begin to feel the joy, pain or anguish of the particular character for yourself."

"To tell you what he's like in one word: just AWESOME. Oh, shite, that's two words. Oh well, he deserves every last one of my well meant words."

"I agree with all the other posts about why David is such an incredible actor. I had seen him in several movies before PoA and was always impressed by how he so completely took on his roles and made them something new every time. -- David (Thewlis) was simply the perfect person to pick to play an intelligent, kind and very sad man with a dark secret. I don't know if anyone else could have brought the conflict and depth of his character to life the way he did."

"I think he's got the most beautiful face when he smiles. I love his eyes and how they sparkle. His voice and ability to do accents and make you believe he's from Northern Ireland, Austria or where ever the heck. He can be smooth and cool like Freddie Mays, vile and repulsive as King Einon, cheeky and full of energy like Dan Starkey and sweet, kind, heartbreakingly adorable as Professor Lupin!"

"How do i like thee? Let me count the ways:
1. He's excitingly CUTE, in ALL angles!
2. He has the sweetest smile AND that melts me!
3. He has the most beautiful hands! I'd kill just to touch those hands!
4. With or without his facial hair, he's CUTE!
5. He has a gentle voice....
6. He did a terrific job in SYIT (what an acronym, enough to describe Brad's accent in that movie). No wonder, the girl chose him over Brad.
7. He has the coolest Brit accent in Black Beauty. Do I have mention he's a cutie in that flick?
8. He's CUTE, even with scars, tattered clothes and all in HP3.
9. His presence in Timeline is enough to compensate for the awful storyline and script.
10. How can you NOT like a man with a fantastic sense of humor? He coined the title "Defense Agains the Dark ARSE" teacher... LOLOLOLOL!
11. He gives his girlfriend a piggy-back ride.... in public!
12. He's ultra-talented (actor, director, writer...DADA teacher)
13. He's BRITISH! (I'm an anglophile, btw)
14. ok, HE'S HOT!

"David is HOT, SEXY, FUNNY, BRILLIANT, and most of all when he's on screen, no one else matters. He just mesmerizes you and completely steals the show. He's incredibly natural and nothing he ever does seems forced or acted...it all seems in the moment, realistic and perfectly believable, and that's what makes a true performer. He really should've won an Oscar for Naked."

"Hmm... because he's an incredibly versatile actor who always puts himself fully into the role. He's lovely looking, has a gorgeous smile, perfect hands and a great voice."

"But the one that's made me love him the most is definately PoA; I think it's because he's such a fantastic male role model - i don't have any guy that stands out as a great role model in my life, but he really made me care about lupin."
