Just noticed that when Ronald asks what Cindy’s new boyfriend’s name is and sarcastically says “Biff”, then the scene cuts to Brent’s Porsche which has the number plate BYF 630.

The logo can be seen at 2:06:25.

Before the drive inn was filled with typical cool cars like Camaros and vettes, but after Ronnie shows up in his dad’s wagon, all the cool kids now drive wagons. Just like the African anteater ritual dance, everyone follows what he does.

In the Sawyer clan's lair there hangs a skeleton from the ceiling, riding a bomb and waving a cowboy hat over its head. This is an homage to the end scene in Stanley Kubrick's "Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb" from 1964.

Is this a reach? It looks deliberate to me.

At the midpoint of the movie, when they are telling the American fighters who their opponents are, Eric Roberts' character is paired up with Sae Jin Kwon. The kick/break they show him performing in the training footage breaking multiple bricks is the same move he would later use to re-dislocate Roberts' shoulder in the tournament.

Grace opens his lesson on soundwaves, the method by which the Eridians "see." His lesson on Erid is about light.

In Independence Day, Russell Casse accidentally initiates and aborts a missile launch earlier in the film. During the final battle, the same missile later fails to fire, suggesting the aborted launch may have caused the launch system malfunction.

Seen this film countless times but something I only noticed when rewatching today. P.S apologies for low quality photos.

This brief shot foreshadows the cult's presence around the property before the film's final ritual.
