Congrats Sandra Bullock -- one of my favorites both as an actress and person!
I have long followed Sandra Bullock's movie career -- I just enjoy her honest, unpretentioius, girl next door beauty! (Not to mention the fact that we are the same age and she looks great for our age--no matter what she's wearing). She has a quick dry wit that I get.
I laughed at her in Demolition Man (1993) with Sly Stallone, and marveled at her in her breakout role in Speed (1994) and admired her freshness ever since (good or bad movies). I have even watched The Net (1995) several times (it soothes my inner computer geek). She is generally the girl next door in her roles which I think is why The Blind Side finally let her shine with acting maturity.
If you are looking for a popcorn and Bullock night, try Speed, Hope Floats, and The Proposal to enjoy her range.
