The trailer for Clint Eastwood’s take on “Jersey Boys” is here, and the movie looks terrific. At first I thought Eastwood was an odd choice for directing this film. But the trailer is lively and fun. Plus the story is well told by Marshall Brickman, who wrote the book for the musical, and John Logan, whose polish of the script looks like it’s sharper than ever. Christopher Walken co-stars. But the big news is that John Lloyd Young, who originally played Frankie Valli in the Broadway show, was cast instead of bringing in a so-called Hollywood Star. Cool stuff. “Jersey Boys” opens June 20th and should be a blockbuster July 4th hit.
