If Infamous is overlooked and underrated it has only Philip Seymour Hoffman to blame. Very bad timing for a pretty good film.
It's amazing to watch to different takes on the same story. Whereas Capote was more of a darker film Infamous is more lighthearted as the relationship between Capote and Perry Smith (Daniel Craig-yes, James Bond).
Infamous has some very good acting in it with Jones pulling off a Capote that is as equal as Hoffman's. The real surprise was Sandra Bullock as Harper Lee. In this film Bullock has gotten away from the pseudo action pictures and chick flick crap she usually frequents. A real stand out performance.
The main problem with Infamous is how the story unfolds. As the tale continues to unwind before you the audiences is suddenly hit with a Larry Kingish testimonial on what happened and what it meant totally destroying the flow of the film. Compare it to pulling the emergency brake on a train that doesn't stop at Tucom Cari causing the once peaceful and moving train to come to a violent halt. A total distraction.
At the end of the Capote vs. Capote match I have to go with Capote. Infamous is a decent film with some good performances (Bullock's being the best) it has the feel of a made for TV film, which isn't a good thing.
Daniel Craig's rendition of Perry Smith is outstanding.
Also, Toby Jones plays Truman Capote much more sensibly and with a sprite that was lacking in Hoffman's portrayal of the tortured author. Sandra Bullock takes over Harper Lee's character and brings a renewed effervescence to its core and nature. One of the murderers is portrayed; more effectively, by the brooding Daniel Craig (who makes a much better criminal than he does Bond-like hero.)
All in all, the movie is a rehash but brings out some interesting points and sheds new light and perspectives on them. It plunges further into Capote's tribulation with wanting to mix fact with reality in order to create a story that, ultimately, he found more appealing and worthy of his audience's attention. Watch the movie if you want, but don't compare it to anything else out there that may resemble it.
