HDTV Heads-Up: May 5-11

✮ The networks are resorting to HD movies to patch up mid-season programming holes: TV3 will use a season of action movies to shore up Monday nights, starting with a re-run of Taken on May 7 — two days after repeating AVP: Alien vs Predator — and Oscar-winner The Hurt Locker (above) will have its network HD premiere, with 5.1 audio, on May 10 (TV One, 8.30).

✮ Sundays will be a double-happy night for fans of The Big Bang Theory when TV2 adds a second season-one re-run to the schedule — the low-rating Happily Divorced is being ditched, one week into its second season, for the extra post-Mike & Molly episode from 8pm on May 5.

✮ Shortland Street’s winter season of hour-long Monday episodes begins May 7, when Hayley’s true colours are revealed — and ahead of several 20th anniversary specials slated for later in the month (TV2, 7.00).

✮ Shorty stablemate Go Girls has its fourth-season finale on May 8 (TV2, 8.30).

✮ TV3 will build on its 7 Days stable of hits with Funny Roots, a series about stand-up comedians mining their comic ancestry that starts 8pm on May 8 with Steve Wrigley chewing over his Dutch genesis.

✮ TV One’s scheduling shake-up continues with Harry’s Law being dropped from 9.30 Wednesdays, three episodes shy of the season-two finale, and replaced by Castle — which is being bumped from 8.30 for a new run of Undercover Boss on May 9.

✮ Life After Death, the episode of The Finder that Bones star David Boreanaz directed, will air on May 10 (TV3, 8.30) — the same night Fringe returns for its fourth season (TV2, 10.30).

✮ Jeff Goldblum and Broadway star Brian Stokes Mitchell will make their debuts as Rachel’s gay dads on the May 11 episode of Glee (TV3, 7.30).

✮ Sherlock will screen here in HD for the first time when season two starts on May 11 (TV One, 8.30) — only days after TV2 airs Sherlock Holmes as its Sunday Premiere Movie (alas, in elementary SD which the network now says will be in HD, too).

✮ The same night Zac Effron, Matt Le Blanc and Not Going Out’s Lee Mack will be on the couch with Graham Norton (TV3, 8.30).
