very and very funny film . steve martin be probably funnier here than in any of his other role a small time thief vinnie antonelli who get place under witness protection program to testify against some big crook . rick moranis also have never be more appealing a the unfortunate agent who handle vinnie affair . of course and my blue heaven be not credible for one moment but it never stop with the joke which come fast and furiously and work for the most part . the script be superbly write in term of hilarious dialogue and one quotable line after another . everyone involve aim at give it their best and even joan cusack be likable here . if you want to switch off your brain for 90 minute and have a few laugh and i recommend my blue heaven . work for me every time .
