He nailed it!
Dickie Attenborough delivered a superb biopic in Gandhi, but Chaplin defeats him. I think it's probably because there were just TOO many things in Chaplin's live to cover them adequately within a single films. Dickie skims over girlfriends and wives in minutes, productions of famous films is seconds, and name-drops other famous figures with abandon ...and little finesse. Most references to Charlie's famous connections - sexual, professional, political - seem perfunctory and not inspired.
I liked the intro in London sequence, and the Mack Sennett stuff was great, yet I was left knowing little more about Mr. Chaplin than when I came in - a driven, workaholic comic genius with an unhealthy attraction for really young women.
RDJ is absolutely outstanding, particularly in his early scenes, and the final ones under heavy makeup.
But the film itself is little more than checklist of Charlie's extensive professional and scandalous romantic life, and struggles to get to the heart of the Little Tramp, of the creative impulsion and talent that drove this man to become the most famous movie star the world has (still) even seen.
With a checklist like this...Chaplin might not be emotionally engaging, or particularly gripping, but it's never less than interesting.
On the other hand, its not worth a fraction of the celluloid of the films that Charlie himself made in the 20s and 30s.
