That was in Die Hard 3!
No, Die Hard used 5 and 3 gallon buckets to make 4 gallons, and the solution for that is a bit different. For that one you simply pour the 5 gallon into the 3 gallon, leaving 2 gallons in the 5 gallon. Pour the 2 gallons into the 3. Then fill the 5 up again and pour what you can into the 3 (one gallon), leaving 4 gallons in the 5 gallon container.

That bugged me in Die Hard because they didn't explain the process fully. So I had to mess around with the problem for a few minutes until I figured it out myself.
