Big (ABC, 9-11:06 p.m.): A 12-year-old kid's wish comes true when he wakes up one morning as a full-grown man and finds there's more to this adult business than he bargained for.

Doing Time: Life Inside the Big House (HBO pay cable, 10-11 p.m.): In this harshly explicit documentary on Pennsylvania's Lewisburg prison - one of only three maximum-security federal penitentiaries - Emmy-winning filmmakers Susan and Alan Raymond use cinema-verit'e to explore life in a ``tomb for the living.'' Even with grim expectations, the show will prove shocking in its details - and in what it says about our prison system.

Bull was building the world's longest-range cannon for Saddam Hussein when he was murdered in Brussels. Did Israeli intelligence do it? This documentary produces new evidence in trying to answer this and related questions.
