The film was photographed by John Toll , who shot `` The Thin Red Line , '' and he gives it a look to compete with the Vietnam movies it has in its sights ( `` Platoon , '' especially , gets a ribbing ) . Robert Downey Jr. : `` Tropic Thunder '' does n't always hit , but when it does , pow ! Tom Charity particularly good in Vietnam satire . Film 's third one particularly strong , though it gets repetitive .
