Twenty minutes into the Down Under superhero satire, you find out that the filmmakers weren’t content to merely make a failed comedy, but a failed musical as well. It’s a startling revelation that unnerves you immediately … and it only gets worse from there.
It’s a shame, because The Return of Captain Invincible has a worthwhile premise and could’ve been an entertaining effort if it weren’t for the filmmakers’ stubborn insistence on fucking the whole thing up every chance they get.
Alan Arkin plays the title character, a once-great superhero reduced to an alcoholic mess after being forced to testify in front of McCarthy’s House of Un-American Activities Committee. Now a bum living in Australia, he’s called back into service by the President of the United States to find and stop the mastermind behind the theft of a powerful hypno-ray. Said mastermind turns out to be Invincible’s arch-nemesis, Mr. Midnight, who — as performed by Christopher Lee — has the film’s only semi-successful musical number (and even here I’m probably being a bit too generous).
Beyond a lazy script, lackluster direction and horrible songwriting, the movie’s biggest flaw is the casting of Kate Fitzpatrick as the female detective who lures Invincible out of retirement. Not only is she a terrible actress, but she also has all of the sex appeal of a Maude-era Bea Arthur, which would be fine if the filmmakers weren’t constantly ripping her shirt off, having her walk around without pants on and generally portraying her as being far more attractive than she actually is.
Because of the subject matter, you might be tempted to watch this as a double feature with Hancock. Fight that temptation — with all of your will and might. —Allan Mott

The main difference between them is that Class Reunion was marketed as a straight comedy, which it constantly (and depressingly) attempts to be, while Slaughter High was marketed as a straight horror film, despite the fact that a combination of the filmmaker’s incompetence and contempt for the audience makes it play far more like an unsuccessful spoof than a typical slasher movie.
Yes, Yankee Doodle in Berlin is silent, but don’t go away. Let me tell you about it. It’s different. Really.
The comedy comes from shameless slapstick and the conceit that the Kaiser is nothing but a henpecked husband who is constantly under the thumb of his frau (Eva Thatcher). Add that to the propagandistic notion that Germany was being ruled by numbnuts and idiots (played by silent comedy stalwarts Ben Turpin, Chester Conklin, Bert Roach and others) and you have a fast-paced 58 minutes of funhouse slapstick that makes Mel Brooks look like Alan Rickman. 
Most of the film’s problems with volume and tone can be blamed on a young Jonathan Demme, who at this point in his career hadn’t developed the sure hand at comedy he would later show with 
He gets a job as an efficiency expert working for his uncle whose company has landed a contract to build missiles for a Middle Eastern principality. Problem is, Uncle Bertie (Dennis Price) wants to lose the contract, which he underbid, so it will go to his nefarious pal Sidney De Vere Cox (Richard Attenborough), whose company will make a fortune to be split between the schemers.
