Comparison between "The Departed" and "Infernal Affairs"

Infernal Affairs is directed by Andrew Lau and Alan Mak, it is a Hong Kong film and very famous film in China.

The Departed is directed by  Martin Scorsese, who is a famous director, the film is inspired by Infernal Affairs. I will compare these two films in following aspects:

The culture:

IA shows the buddhist culture in China, from its Chinese name "wu jian dao", the Chinese culture focus on implicit. The D shows the same story directly,and shows the fate of many characters in this movie and the final outcome. So the American culture is directly.

The actors:

IA uses a lot of famous Hong-Kong actors. In acting, Tony is more introverted psychological drama, he can just use a forced smile to show the situation without hoarse and tears. In The D, Leonardo DiCaprio plays the role in more active way. His body language is very rich, his tangled facial muscles, exaggerated body movements. 

The expression:

The difference of the two films is a direct response to differences between Eastern and Western cultures, oriental culture emphasizes subtle, seemingly ordinary word but hidden deep mystery, while Western culture is more emphasis on direct visual impact.

So those are my findings, it is interesting to compare two films which the story is same. And I also learn the body language in acting an undercover. It is helpful.
