What is your favourite movie starring Robert Downey Jr and why?

It's tied for me between

Sherlock Holmes, where, as said before, we can see his HOT HOT body and a lot of action scenes and all...

and

Kiss Kiss Bang Bang (on the picture) because his role is just soooo funny, he's like some kind of idiot and the movie has such funny jokes, I laughed the whole time. Moreover, there are a lot of good action scenes and suspense... IT'S SO GREAT!

Mine's Sherlock Holmes because we get to see his AWSOME body!! [OMG Soooo amazing!]

SHERLOCK HOLMES: great performence, just like I imagined Holmes =)

KISS KISS BANG BANG: super funny ^^

I would say ironman because he really came back and showed his fans that even after rehab he is back. he worked really hard to bring that character to life. plus hes smoking hott in it lol ;)as you can see in the pic haha

Very tough question hmmm... I've seen plenty of his movies and I must say my fav would have to be Fur just cause I think the character was really great and he did an amazing job when for part of the movie all you saw of his face were his magnificent eyes.

I love the movie Only You, he was super scary in the movie in Dreams... and i love his acting in Sherlock Holmes.

Charlie chaplin robert downey jr was fantasic one of his best rolls and really funny

IronMan y IronMan 2 Por Que le demostro al Mundo Apesar Que lo vivido e Hispana y Su sobreventa Talento le dio una esperansa Otra fans SUS párr volver una y Su barba de candado amarlo lo hace sexy Por lusir ESO lo amo y soy fan Gran demostro tambien paul Que Larry no era de El Unico párra amar :):):):):):):):):):)):):)

I'd say Kiss Kiss Bang Bang because unlike his other roles, he seems to show his humour through his role. Don't get me wrong, Iron Man and Sherlock Holmes are probably the highlight since his rehab stunt, but the comedy that was enveloped into his performance is evidently shown. x

All of them of course!!! Duuuu!!! There's no doubt that all his work is simply the best!!!

All his movies are absolutely AMAZING but if I had to pick 1 ........ has to be Iron Man (1 & 2) but Sherlock Holmes comes a very close second.

Have to say ..... this man just gets more and more sexy with age ..... Mmmmmm

My favourite movie starring Robert Downey Jr movie is "Charlie Bartlett" because he plays an everyday role as Principal Nathan Gardner and it shows his gradual decline in his life.

My favourite movies with RDjr are "Chaplin" and "Sherlock Holmes" (part1). Chaplin was a greatest figure on screen for ever, and Robert was very excellent playing him. Holmes is a new step in series of movies about this charackter, and so Roberd shows in this role best of his talent. SH-AGOS is not so good IMHO.

It's deffinately Sherlock Holmes!
I think he is just made for this rule! - Especially in combination with Jude Law one can see his awesome acting taltent... Furthermore its the movie i can watch over and over (not only because I'm totally Downey obsessed...^^)
