Ghosts of Girlfriends Past HBOE 8:00 pm ET

Matthew McConaughey milks his well-established romantic-comedy persona yet again, within an amusing premise. He plays a commitment-phobic photographer who's reunited with a former flame (Jennifer Garner) at his brother's (Breckin Meyer) wedding -- but he also encounters ghosts representing the past, present and future of his very active love life. Michael Douglas also is enjoyable as the specter of the McConaughey character's late uncle.

After making "The Bridge on the River Kwai," director David Lean and producer Sam Spiegel reteamed on another epic, the saga of World War I officer T.E. Lawrence (Peter O'Toole, in his movie debut).

Screamers: The Hunting SYFY 9:00 pm ET

It's anybody's guess why someone would bother pouring money -- OK, not much money, but still -- into a sequel to a largely forgotten 1995 sci-fi horror flop, and this gore-soaked but otherwise unremarkable 2009 "Aliens" wannabe, about a rescue team that encounters a race of murderous half-human, half-machine hybrids on a distant planet, will not leave you any the wiser. Gina Holden, Jana Pallaske and the ubiquitous Lance Henriksen star.

The Nanny Diaries LIFE 9:00 pm ET

This 2007 dramedy wasn't well-received by critics, maybe because of its uneven tone, but if you've ever had a demanding yet useless boss, this is a film you'll understand, at least.
