On Demand movie highlights

This Is the End

(Comcast Movie Collections: Just In) A cheerfully crass meta-comedy in which the Apocalypse comes to Hollywood and takes most of the A-list with it. Seth Rogen, James Franco, Jay Baruchel, Jonah Hill, and others play comic versions of themselves. The opening scenes are inspired, but then the world ends and the movie still has an hour and a half to go. (R; runs through Jan. 1)

Ty Burr

Under the Tuscan Sun

(Encore on Comcast) Writer-director Audrey Wells’s film version of the Frances Mayes bestseller is a shamelessly enjoyable fantasy about an American woman (the gorgeously normal Diane Lane) who gets a mid-life makeover when she buys a villa in Italy. Every cliché in the travel pamphlet is here, and it all goes down like limoncello — sweet, not very good for you, but irresistible just the same. (PG-13; runs through Jan. 9)

Ty Burr

King Arthur½

(Starz on Comcast) It does to Arthurian legend what “Troy” did to Homer — trashes it — but at least it’s a rousing piece of headcheese, equal parts “Gladiator,” “Braveheart,” and Hollywood hooey. Clive Owen makes a stalwart moper of an Arthur, while Guinevere is played by Keira Knightley as a warrior chick. Antoine Fuqua directs segments with startling finesse, but it’s a Jerry Bruckheimer movie in simpleminded word and deed. (PG-13; runs through Feb. 6)
