Determined to take advantage of the attention currently focused on its Marvel brethren, “The Avengers” — and to not be overshadowed by the highly shadowy “The Dark Knight Rises” — the third trailer for “The Amazing Spider-Man” has now made its debut.

With it comes a tad more footage from Marc Webb’s Peter Parker reboot than we’ve seen in the previous two trailers: some additional Peter (Andrew Garfield) and Gwen Stacy (Emma Stone) moments, a little more Lizard (Rhys Ifans) and additional indicators that this comic book adaptation will contain big-scale action and destruction.

But there was one snippet of a scene I wish Sony hadn’t included in this trailer. (Warning: A minor spoiler lies ahead.)

There’s a bit in the trailer where Spidey confronts a car jacker and cracks a couple of jokes, including one about how the guy has found Spiderman’s weakness. “It’s small knives,” he says, faux-cowering before the thief, then immediately slinging webs at him.

It’s a little moment, but one that I suspect will get a big laugh during the actual film. And it’s the kind of thing I wish I hadn’t seen in the trailer. In movies like this, the unexpected humor and tinier delights are what often provide some element of surprise after months and months of hype.

Imagine if “Spider-Man 2” had existed in the age of Twitter and excessive trailer-nalysis. Sam Raimi might have been tempted to include a portion of this brilliant montage — which remains one of my favorite moments of the modern comic book movie era because it was so fun and absolutely out of left field — in one of the trailers.

And that would have robbed us of the joy of discovering that a Spider-Man movie had improbably decided to borrow a page from “Butch Cassidy and the Sundance Kid.”

The “small knives” scene is a small moment in the trailer. So maybe I’m nitpicking. But I really want to like “The Amazing Spider-Man,” and I want to like it because when it comes out on July 3, it feels like we’re seeing the Spidey story for the first time.

Is that possible with a reboot, or with any movie these days that is required to relentlessly market itself and bombard us with sneak peeks? Honestly, I’m not sure. But I still like to think so.
