LOS ANGELES - The shoe phone on TV's

wasn't just a sneaky spy gadget, it was a technological marvel: a wireless, portable telephone that could be used anywhere - though it did require a dime to make a call.

Today, almost everyone has a pocket-size version that also takes photos, shoots video, sends e-mail, and surfs the Internet. About the only thing it doesn't do is protect your feet.

comes to the big screen next week, along with a spate of new spy gadgets to help Maxwell Smart, Agent 99, and the other spies at CONTROL. The gadgets are just as goofy as they were in the original TV series, but because technology has caught up with the writers' imaginations, there's a big difference: many of the movie's doodads actually exist.

"Our favorite thing is to take something that does sort of exist and just exaggerate it a little bit," said Matt Ember, who cowrote the script.

The film shows a tiny iPod alongside spy-worthy stuff such as a two-way tooth radio and a digital "spy fly" - all of which are available now.

"It's pushed to a level of success that perhaps it hasn't achieved in the real world, but it's real, it's out there, so that's fun" added cowriter Tom J. Astle, a self-described science nut.

Director Peter Segal said he originally couldn't believe such devices were real.

"I said, 'That's too silly. I don't think people will buy it,' " he recalled telling the writers. "Then they Googled it and it came up as an actual thing."

Astle and Ember saw the tooth radio in a magazine and thought it was a perfect fit for the film.

"That's an example of taking inspiration from the old series in spirit," Astle said. "The inherent comedy of having a microphone in your mouth - it's really close to your voice and it's easy to yell and be too loud."

The inextricable link between gadgets and spy movies began with James Bond in 1962, said TV historian Tim Brooks, author of

. The often-preposterous devices Bond used added levity to a genre that "had always been deadly serious" during the early years of the Cold War, Brooks said.

ratcheted up the goofiness level with bulletproof pajamas, a Bunsen-burner phone, and other wacky gadgets that often didn't work. When the show debuted in 1965, the nation was future-focused and obsessed with the promise of technology.

The show played on that obsession, Brooks said, introducing dozens of covert gadgets and props designed to make life easier for Cold War-era secret agents. A cigarette lighter doubled as a .22-caliber gun. A lipstick could record conversations or release poisonous gas. Then there was the famous shoe phone and the always-dysfunctional "cone of silence" that could (theoretically) keep conversations private, even in a crowded room.

"It's nothing that you would expect to find or would even make sense in real life, and that's the gag," Brooks said.

The movie also takes liberties with some familiar devices, such as portable lasers, retinal scanners, and a tricked-out Swiss Army knife equipped with a flame-thrower and a mini crossbow.

"Human beings are tool-users," Astle said. "We would like to believe that our government - the good guys - have within their power tools and electronic gadgets that will protect us that are beyond what we could do."
