i enjoyed the movie avengers and i really like the Iron man character 
Robert Downey improvised a lot of iron man scenes
I guess he was one of the few actors allowed to do so. he is that talented
Downey was raised in artist background
oh wow... maybe thats where the talent comes from, when did he start acting 
He started in his fathers films in the 70's/
oh nice, was his father a director?
He was a underground director who gave his son his first part
thats awesome, his son turned out to be great.
He has won a few golden globes
