Old men urinating too often. Hollywood script or real?

Unfortunately, real. Although it's often played for laughs (zoolander and a colorful comment about a tikitorch come to mind), many guys have problems with urination as they get older because their prostate gets bigger. The larger prostate prevents the bladder from emptying completely, so you're always feeling the urge to urinate, even if you can only manage a dribble. Sad but true. Hope this helps.
