Well, for Comedy, I think that "What's Up Doc" with Barbara Striesand is great.
"It's a Wonderful Life" with Jimmy Stewart has to be listed as one of the best movies.
"The Possiden Adventure" the original.
"Titanic" with Leonardo De Caprio I think is fantastic. I know nearly all the words to it.
But currently, I really like "War of the Worlds" with Tom Cruise.
These movies are good for entertainment. I think that they are well made without the mistakes a lot of movie makers do these days, in adding something stupid to the movie, making it less than what it can be.
