Tropic Thunder

As far as comedies go, Tropic Thunder has to be up there with the best in recent times.
It's not intelligent comedy like in a British film but it's still a riot as Ben Stiller takes the mickey out of war films (and several other types) in a much needed return to form.
Stiller is action hero actor Tugg Speedman who has been cast in a film about the Vietnam war along with several other noted actors of his time. Jack Black is his usual crude self as Jeff Portnoy and Robert Downey Jr is outstanding as the multiple Oscar winning Australian Kirk Lazarus (who tends to remind you of Russell Crowe now and then).
Cameos abound here and none better than from Tom Cruise, much to my surprise, as film magnate Les Grossman. He's hard to describe and you kind of have to see it to believe it. He really has made a good move doing this film.
Others include Matthew McConaughey, Tobey Maguire, Jennifer Love Hewitt, Mickey Rooney and, hilariously, Lance Bass.
The laughs start before the opening scene when we see the four main leads in advertisements for their products or films and it's a great intro because it gets you in the mood to laugh.
This ain't rocket science, it's a shade crude at times and a little offensive depending on your sensitivity but it's just good fun.
There's no deep and meaningfuls here and Ben Stiller does his best work since probably Zoolander even if his character does remind you of that character.
A very funny 8 out of 10, better than your average silly comedy.
