This year, Hogwarts is hosting the Tri Wizard festival, and there may be a plot afoot to off Potter (Daniel Radcliffe) during the proceedings. Hermione (Emma Watson) finds a man worthy of her in competing Russian Quidditch champion Viktor Krum (Stanislav Ivaneski), to the chagrin of Ron Weaselly (Rupert Grint) who, though growing into a fine, shaggy orange-haired figure of a lad, is still not quite mature enough to ask Hermione to the Yule ball. Krum's teacher may be involved in the dastardly get-Harry plot, which involves writhing snake tattoos, skull clouds, death-eaters, tournaments with live dragons, a submersible schooner, and a competing school of poised and beautiful girls run by Maxime (Frances De La Tour), who shares a romantic past with gamekeeper Hagrid (Robbie Coltrane). All the other favourites of the series are back as well, including Alan Rickman, Michael Gambon, Maggie Smith, and Gary Oldman, with Timothy Spall as the odious Wormtail, while a new addition to the A-list thespian roster is Ralph Fiennes.
For five years, Superman (Brandon Routh) has been away from Earth, coaxed into space by a belief that Krypton may still exist. Finding nothing, he comes back to a changed world--not only has terrorism become rampant, but Lois Lane (Kate Bosworth) has married, started a family, and won the Pulitzer for her piece 'Why the World Doesn't Need Superman'. After a stop in Smallville to see his adopted mother (Eva Marie Saint), Superman is back in Metropolis, and Clark Kent has his old job back at the Daily Planet, with everyone still incredibly oblivious to his alter ego. But where there's Superman, there's Lex Luthor (Kevin Spacey), and he is likely to be planning something dastardly--in this case, using a piece of pilfered kryptonite to grow an entirely new continent that he will control. Bryan Singer (X-MEN 1 and 2), armed with a script by Dan Harris and Michael Dougherty, approaches the red cape with reverence for the lore of the character, and respect for Richard Donner's SUPERMAN (1980) and Richard Lester's 1980 sequel, films that ushered in the era of the modern superhero film. Singer's SUPERMAN is filled with melancholy, and not so subtly suggests the notion of Superman as a Christ figure, sacrificing himself to save mankind. But there are still laughs, mostly courtesy of Spacey (clearly having a blast) and Parker Posey as his moll, Kitty Kowalski, as well as plenty of gasp-inducing set pieces, including a spectacular and terrifying near plane crash and a sinking boat. While modern visual effects have allowed Superman to reach entirely new realms, Singer keeps them from becoming the film's raison d'etre, thus keeping the Man of Steel's gigantic heart intact--heavy though it may be.
