For men of a certain age, Caddyshack is pretty much indispensable. While not as big a box office hit as Animal House (which sprang from some of the same creative minds), it stealthily redefined comedy with a series of completely off-the-wall scenes that are quoted to this day.

But as wacky as the movie is, the story of how a bunch of rebellious, often-drug-addled upstarts made it is even more surreal. At least, that’s how Entertainment Weekly film critic Chris Nashawaty tells it in Caddyshack: The Making of a Hollywood Cinderella Story, an exhaustively reported, thoroughly entertaining book about the birth of a unlikely cult hit. (Oh and like the film itself, it has a surprising amount of heart, too.)

Did you know that Bill Murray‘s character, Carl Spackler, did not even appear in the original draft? Or that 58-year-old Rodney Dangerfield loved weed and coke as much as his twenty-something co-stars? Or that Barbara Streisand’s hair stylist/boyfriend came up with the idea of turning the gopher into a half-million-dollar animatronic sensation?

That’s just some of the fantastic stuff you’ll read in this peach of a book, which we at Made Man devoured in less than 24 hours. Grab a copy for yourself (and hey, maybe a Father’s Day gift, too), and we dare say you’ll approach total consciousness, which is nice.

And if you just can’t get enough, listen in as the hosts of our favorite podcast, Six Pack, interview Nashawaty on their latest episode! (Well, we’re waiting…)
