NEW YORK. “Never was there such a dog,” says grizzled Yukon explorer John Thornton (Harrison Ford), admiring the antics of Buck, the canine star of “The Call of the Wild” (PG, Twentieth Century).
Indeed not. For the Buck in this, the seventh film adaptation of Jack London’s 1903 novel, is a computer-generated marvel, a big sloppy St. Bernard-Scotch Collie mix as lifelike and convincing as the creatures in recent CGI films like “The Jungle Book” and “The Lion King.”
