Both are very good choices. "Year One" could be added too.
But then it depends on what sort of strain you are smoking and what your mood is. If you are in an introspective mood and want to become deeply engrossed in a storyline rather than just laugh at what you are watching, the OLD black and white Otto Preminger film "Anatomy of a Murder" is great.
To date the courtroom scenes are considered to be among the very best ever filmed and the most accurate. The man playing the judge was a Michigan State Supreme Court Justice brought in to see that the scenes were technically accurate and he ended up playing the judge.
I also like it because my Uncle Bill Cooley played the court recorder. (The guy in the court room without a single line taking shorthand left handed.) It was filmed on location in the U.P. and a fair number of locals were used and it adds a realism that many flicks lack. Jimmy Stewart was great, Arthur O'Connell was great, Lee Remick was great. George C. Scott was great, Eve Adren was very good and Ben Gazzara was very good.
It's a totally different viewing experience than modern movies but if in the right mood it will grip you and not let you go.
"Zack and Miri Make a Porno" is pretty decent as is "Clerks 2."
