For fans of Hollywood, there’s plenty of insider humor. Jay Baruchel’s meaningless yet hilarious monologue about the Blu-ray/HD DVD war is bound to draw laughs from anyone who was part of that battle. Numerous actors are called out by name (Sean Penn for I Am Sam), and the film has no problem making fun of itself numerous times.
Even if you’re not “into” Hollywood and some of its inner workings, there’s still plenty of comedy to be had from Tropic Thunder. Yes, some of the better parts would be over your head, but the snappy dialogue and absurdity of the situation still make for a fine over-the-top comedy worth your time. 
“Wow.” That’s the first impression of this incredible Blu-ray. This is a marvelous, incredibly detailed, bright, and vibrant presentation. Colors pop off the screen, black levels are flawless and rich, and the clarity is overall some of the best yet seen on the format. If there’s any complaint, it’s that the contrast can run a little hot, particularly on long shots involving greenery. It’s a minor overall complaint. 
TrueHD is the choice of audio formats here, and the 5.1 mix is alive with positional audio. Dialogue is consistently well mixed, and always audible over the action. Bass is the type that rattles rooms, and even non-action scenes deliver bits of ambient audio. Heavy action delivers on all fronts, and gunfire is distinct in every channel.
Tropic Thunder is loaded with featurettes, though things begin with two different commentaries. Ben Stiller leads the first along with his filmmaking team, and then again joins the main cast for their take on the movie. Four featurettes focus on pyro, the opening action scene, a basic script feature, and the sets. Each of the cast members is given their own piece, split into seven sections and running for 22 minutes total.

While Cruise got a lot of deserved praise, I thought McConaughey was hysterical throughout.

i actually thought jack black stole every scene he was in. the scene of him tied to the tree had me actually laughing out loud. how he can make fun of himself to make the scene work better shows his confidence and vulnerability. the movie wouldnt have been the same without him.
