As I sink back into the rhythms of life in Toronto — screening, writing, screening, writing — I find myself doing what I always do, trolling the interwebs for things to read when I should be working. And there’s some great stuff here.

At The House Next Door, contributor and actual research scientist (!) Simon Hsu offers an excellent list of Scientists on Film for the site’s 5 of the Day feature, collecting five films that depict scientists and their laboratory environments in an honest and/or accurate manner. The highlight for me was his inclusion of Douglas Trumbull’s “Brainstorm” — a deeply, deeply flawed film that still manages to be quite thrilling when depicting the research, development and marketing of the high-tech device that drives the film’s plot. (Which isn’t necessarily what Trumbull was going for, but still.)

And then there’s the fine discovery that Mike D’Angelo will be contributing to the Onion AV Club beyond his excellent Cannes reports — starting, I believe, with this intriguing meditation on what he thinks Michael Mann might have been trying to do with the notion of celebrity in “Public Enemies”, and whether or not Mann achieves his goals. It’s a really good read, even if you believe — as I do — that “Public Enemies” is both Mann’s least and worst film.

Right. Off to the first screening of the day, then … and then, once that’s done, I can allow myself to read the comments thread.

The hard numbers won’t be in until later today, but right now it appears that the third “Ice Age” and the second “Transformers” are tied for first place at the North American box office, each of them pulling in $42.5 million over the weekend.

When the final tallies are reported, my money’s on “Ice Age” to come out on top — it was the much stronger performer on Wednesday and Thursday (its five-day gross is $67.5 million to the “Revenge of the Fallen” take of $65 million), and its 92-minute running time means considerably more screenings per day than the 149-minute expanse of the “Transformers” sequel.

Meanwhile, “Public Enemies” made $41 million in its first five days — Michael Mann’s best opening ever, according to the Variety piece, and “a testament to Depp’s appeal, proving he can open a pic even when not dressed as a pirate.”

Poor Christian Bale. He’s already over, isn’t he?

Something to entertain you while I’m running around looking for sticky buns, Chex Mix and out-of-print DVDs: My latest Sympatico/MSN movie gallery, which uses Johnny Depp’s John Dillinger in “Public Enemies” as a springboard to look at other stars who’ve gone gangster.

Historical figures only, I’m afraid, which means no Corleones and no Father Hoods. But don’t think I wasn’t tempted.

I’m not sure how it happened, but for some reason I had it fixed in my head that “Ice Age: Dawn of the Dinosaurs” opened today instead of two days ago. I dunno, I’m all messed up with times and dates this week. Sorry about that.

“Empty Nest“: Daniel Burman is becoming the Argentine Woody Allen — but the late-70s, early-80s version, where the thematic repetition and calculated flights of fancy were balanced by engaging dialogue and the occasional flash of human insight, so that’s actually okay.

“Finn on the Fly”: You know that thing were a company dumps a middling title into theaters as a kind of promotional run for the DVD? Yeah, this is one of those; in fact, a review copy of the DVD arrived in my mailbox just one day after E1 announced the theatrical release. Susan took it, and was not terribly impressed.

“Ice Age: Dawn of the Dinosaurs“: Those lovable CG mammals wander into an even more prehistoric world than their own, mostly because kids love dinosaurs and Fox really needs to keep the franchise alive. Variety reports strong opening-day numbers from Wednesday (again, oops), which means it’ll crush “Public Enemies” with ease … and maybe even top the “Transformers” sequel’s second weekend.

“Moon“: Lonely lunar worker Sam Rockwell goes crazy — or does he? — on an isolated base in the not-too-distant future. Why he doesn’t just build a couple of wisecracking robot friends, we’ll never know. That’s totally what I would do, if I knew the first thing about robotics. Hell, I’d probably try anyway.

And that sums up the week. Have you seen “The Girlfriend Experience”, “Summer Hours” or “Tokyo Sonata” yet? Because those are really good.

… well, assuming you stay out of the sun and avoid red meat, anyway.

But if you’re going in that direction, I humbly suggest you pass the time with Cinematheque’s salute to the French New Wave: It nourishes the soul, and you’re sure to pick up some style tips while you’re at it.

Oh, and in the spirit of the season, here’s this month’s contribution to NOW’s Hot Summer Guide. And yes, I’m still holding out hope for “I Love You, Beth Cooper”, even if it is directed by Chris Columbus. The book is so good and so simple; how can he screw that up?

Don’t tell me. Just let me believe.

First and foremost: Happy Canada Day, everybody! Maple leaf forever! Be like Joshua Jackson in “One Week” and drink a Steam Whistle today, wherever in the country you may be; apparently, it’s available everywhere.

Anyway. Michael Mann’s “Public Enemies” opens virtually unchallenged today as this year’s big Fourth of July action picture — its only competition for the holiday weekend is the “Ice Age” threequel, and that’s pitched to a very different audience.

Publication schedules being what they are (damn you, Wednesdays!), my NOW review won’t run until tomorrow, so I’ll just say this: In some parallel universe, where Mann’s fetishes and obsessions led him to unlock the secrets of a new digital cinema, this is being hailed as a masterpiece.

The thing is, we don’t live in that universe. And neither does Michael Mann. But he sure thinks he does.

UPDATE: Here’s the review!
