This year's Macworld Expo is unique in a number of ways--it's Apple's last Expo, Steve Jobs didn't giving the keynote, and there are not one but two separate premieres of Macintosh-related feature-length movies. Monday saw the press screening for Rob Baca and Josh Rizzo's Welcome to Macintosh ($20), which will be followed by a public screening on Thursday night. (The second premiere is MacHEADS the Movie, which will be shown on Wednesday night at Moscone.)

I went to the Welcome to Macintosh screening Monday not knowing what to expect--I intentionally stayed away from the Web site, and hadn't seen any trailers for the movie. The movie weaves a series of story threads about Apple, its employees and philosophies, and the Mac together by interviewing people who were there for the launch of the Mac--or the launch of Apple itself, in one case.

Through these interviews, you get a sense of what was involved in the making of the Mac, why Apple's products tend to appeal to their users moreso than do products from other manufacturers, and the personalities of those involved in the products. You'll also learn some interesting tidbits about the Mac and other Apple products, including quite a bit of detail about the original Apple I.

The film consists entirely of interviews with these individuals, interspersed with some shots of various Mac models (including many in interesting locations) and the occasional visual of a Mac's screen. But there's no doubt about the focus of the movie: It's the people--and if you're interested in the history of Apple and the Mac, that's a good thing.

Interviewees include people you've probably heard of, including Guy Kawasaki and Andy Herzfeld. Although these people are well known, they had interesting things to say, and much of it was stuff I hadn't heard before. As an example, here's a clip of Guy trying to explain how Steve Jobs comes up with his ideas.

While these "known" interviews were informative, I found the interviews with the unknowns to be the real gems of Welcome to Macintosh. From QuickTime engineer Jim Reekes (by far the funniest of the interviews) to Oscar-winning film editor Richard Halsey to Wayne Wenzlaff (the first reseller to sign on to sell the Mac), these people really helped fill out the hidden details behind the early years of the Mac and Apple. Here's a bit of Jim discussing his desire to change the startup sound for the soon-to-be-released Mac Quadra.
