The Departed vs Infernal Affairs

I noticed the billboard ad for The Departed since last week but never find it interesting until tonight that I realized it was the Hollywood version of HK's Infernal Affairs. The original movie was an excellent movie with an excellent cast. I wonder if this Hollywood version could match the quality of the original. But I'm sure a Martin Scorsese movie should live up to some expectation. Perhaps the only weakness is the non-matching casting, in terms of experience and status. In the original, both the main characters were played by top-notched actors while this one boast 2 not so top-notched actors. Anyway...this movie (the Departed) is definitely on my to watch list. Here are some comparison photos.
