THE TEMPEST ★★

(Showtime on Comcast) More Julie Taymor-style Shakespeare, full of ‘‘daring’’ frissons but lacking much urgency or point. Helen Mirren makes a solid and engaging Prospera, and the rest of the cast — including Ben Whishaw, Djimon Hounsou, Russell Brand, Alfred Molina, and David Strathairn — scampers about the Hawaiian lava fields enunciating like mad. (PG-13; runs through Aug. 21)

WHAT’S YOUR NUMBER ★★½

(HBO on Comcast) Formula click-flickery — about a woman lamenting her colorful sexual history — that reminds us that Anna Faris lives on Planet Farce and not in Katherine Heigl land. Even so, the application of her fake-ditz lunacy to the pursuit of love has its amusements, mostly when they’re aimed at Chris Evans, a generic hunk whose secret weapon is that he knows how to use his genericness for comedy. He and Faris are ideal for each other. They just need a better movie. (PG-13; runs through Sept. 24)

SPEED ★★½

(HBO on Comcast) The most spectacular argument against public transportation since the Hindenburg went down. There’s a bus rigged to explode if it slows to less than 50 mph, and you could say the same thing of the movie — if you love crash-and-burn, you’ll think you’re in heaven. Good guy Keanu Reeves tries to foil bad guy Dennis Hopper, but the real stars are the explosives experts who provide the big bangs. (R; runs through
