>>>I saw a movie in early '80s. I am still looking for this title. It is a movie about a high tech bank robery which is taking place in Rio de Janeiro during the carnival. I remember there is a special scene in the movie where the thiefs are sychronizing an explosion to match the carnival one so the sound wouldn't be that much heard. Anyone remember that one?

>However, I'm not sure about the bank. It could be a museum. There are wearing infrared lens to detect that and other high end gadgets. It is on the 3rd or 4th floor of the building if I remember correctly. The plan is prepared from the US and they are travelling in Brazil for the big show.

I can't find anything on www.imdb.com Hmm.. I think I might have seen this movie too. I remember a movie where they used mirrors to deflect the infared laser beams.
