"Listening In" is a very frustrating film to watch. On one hand, the difficult to believe plot is very funny and had seriously good possibilities. However, the way the movie handled this funny situation AND the ending really pulled the quality down...way down.
A man is convinced by his friend to come along with him as he goes out with a young lady. Why he wants him along, I have no idea. Would you want a friend tagging along?! Regardless, when a phone call is made, the wife of the married man overhears and thinks her husband is going on a date....not his friend. So, the wife is stinking mad and heads to the hotel where the three some have gone. But there are two things she doesn't know...the friend just married the woman, so going to a hotel is no biggie. And, the husband insists his friend and his new wife use his room, since it's a suite and it is his wedding night.
Now, this situation is a bit tough to believe...I'll admit that. But when the angry wife arrives, you would THINK all sorts of comedy would ensue. Well, it doesn't. Instead, since it's a Mack Sennett comedy, it resorts to ancient and very outdated slapstick...with the wife running about shooting wildly. This just isn't funny and looks like a film circa 1914.
Overall, this one starts very well...and ends rather poorly. Sad...as it SHOULD have been really good.
