The main reason to see Ant-Man is Paul Rudd, once again proving that casting is the chief thing Marvel has going for it in its efforts to capture the comic-book movie world. Like Robert Downey Jr. in the various Iron Man and Avengers movies, or Chris Pratt in his leap to superstardom in Guardians of the Galaxy (James Gunn, 2014), Rudd has precisely the right tongue-in-cheekiness to bring off a preposterous role, one that the end credits assure us he will be playing again. Rudd, whose quick wit is known from his talk show appearances, also had a hand in the screenplay, which was begun by Edgar Wright and Joe Cornish and revised and finished by Rudd and Adam McKay. For once, a comic book film is better before the CGI flash-and-dazzle take over -- the concluding portion of the film is a bit of a muddle, considering that most of the performers in the action sequences are ants. Indeed, the most impressive special effects in the movie are not the action sequences but the "youthening" of Michael Douglas, who is first seen as the much younger Hank Pym in 1989, looking much as he did in The War of the Roses (Danny DeVito, 1989), one of the films used by the special effects artists as reference. On the other hand, it has to be said here that Rudd doesn't look much older than he did 21 years ago in Clueless (Amy Heckerling, 1995).
