The mysterious and cryptic early talk about Disney’s “Tomorrowland” (May 22) is that it connected with early ideas that Walt Disney himself had — notes — about the Tomorrowland part  of the theme parks, and a possible movie tied into them.

The third action-packed trailer to the most anticipated movie of the summer suggests something more conventional — effects, action beats, George Clooney yelling “Come on,” and cracking “You ain’t seen NOTHIN’ yet.” But it still seems to connect with Walt’s expansive, fanciful 1950s idea of what the sci-fi “future” would look like.

It looks like fun. And maybe it means they’ll finally update and spend the money on that concept of their parks, using the movie as an excuse. I hope so.

But the movie? It looks like a trip.
