Awesome acting Reference

found this brilliant article on splitsider. of various actors giving there auditions for roles they later won. what i love is how convincing they are, how relaxed but practiced they seem... could study this for hours..

here are some of the questions i asked myself:

- why was michael cera so convincing?

- why was megan fox not very convincing?

- why was dusten hoffman not at all like dusten hoffman in a skirt?

- why am i watching Alyson Hannigan's eyebrows?

- what is it about Audrey Hepburn's pose/face/demeanor that is soo damm appealing?

- above all what makes there performances comedic?
