Pirates of the Caribbean: On Stranger Tides (Disney, Blu-ray or standard DVD, PG-13, 136 min.). The fourth Pirates movie may be on autopilot a bit with some of the swordplay, such that so much of it is stitched together rather than continuous takes anyway, but it is still entertaining enough to watch.

The sense of fun commences right at the start, when Capt. Jack Sparrow’s (Johnny Depp) former right-hand man Joshamee Gibbs (Kevin McNally) is about to be hanged as Capt. Jack Sparrow. However, the real Sparrow hijacks the trial by impersonating the judge. Their subsequent escape is interrupted by King George’s men. The king (a funny turn by Richard Griffiths) wants Sparrow to lead his ship, headed by Sparrow’s old foe Barbosa (Geoffrey Rush), to the Fountain of Youth, before the Spaniards find it. Sparrow engineers a clever escape from the audience with the king and is chased through London — there is a fun cameo by Judi Dench — before meeting up with his father (rocker Keith Richards, whose real-life personality often is echoed in Depp’s performance as Sparrow) in the same tavern where a faux Sparrow is gathering up a crew. That false Sparrow turns out to be an old acquaint Nance, no longer on good terms with Sparrow.

Soon, Sparrow is shanghaied and aboard a ship captained by Blackbeard (a fine performance by Ian McShane), with the first mate being Angelica Teach (Penelope Cruz), a former lover of Sparrow’s who claims to be Blackbeard’s long-lost daughter. Sparrow kind of knows the way to the fountain, but he knows nothing of the ritual that requires two chalices and the tears of a mermaid. To get the mermaid’s tears, Blackbeard puts out a boat of his men as bait, and the mermaid attack that follows is the film’s other highlight. One mermaid is captured (Astrid Berges-Erisbey as Syrena) and she captures the sympathies of hunky cleric Philip (Sam Claflin). From then on, the film kind of blurs together, with lots of swordplay, noise and an ending in which everyone arrives at the same spot but not by the same method, which is very confusing.

The Blu-ray edition looks and sounds super, but more daylight scenes would have helped the film, once again directed by Rob Marshall, who provides audio commentary with executive producer John De Luca. With the Blu-ray edition, one can use the Disney Second Screen to synch the film on your television with your computer or other device to view, via an app, behind-the-scenes footage, visual effects stages and other material. There also is a 3:29 blooper reel that made me laugh a couple of times and five brief LEGO animated Pirates tales. It also comes with a standard DVD version. Grade: film and extras 3 stars

Rating guide: 5 stars = classic; 4 stars = excellent; 3 stars = good; 2 stars = fair; dog = skip it
