If you want to see an Oscar performance from Steve Carell...

Rating: 7/10 (29 December 2014)

.... you have 2 options.
You can, first option, watch this film.
Overlong at 2+ hours, and based on a true (but horrific) story, directed not only like a horror film, but actually BETTER DIRECTION than most horror films today, this quasi-documentary give you an almost unrecognizable Steve Carell playing a man with enough psychological issues to keep an entire med school graduating class of shrinks busy for years.
(Note to reader: did you ever notice how, when ordinary people exhibit mental issues, they are mentally ill, but when the super-rich exhibit THE VERY SAME SYMPTOMS, they are merely 'eccentric')
Carell steals the entire movie from very capable actors, including one of the most subtle performances ever given by Mark Ruffalo, and Mark's picture, I think, actually appears under the Wikipedia entry on "Subtle."
Anyway that is your first option. The film is a work of fine craftsmanship, but frankly as entertainment it is as depressing as a visit to the cemetery.
Your other option to see Oscar work from Carell -- and I think this is the only IMDb review that actually mentions this -- is to get a copy of the animated treat OVER THE HEDGE and watch as Carell is robbed by NOT getting an award for playing Hamilton the squirrel.
Not kidding. Check it out. Have I ever misled you?
