Visible crew/equipment: Near the end when the Coast Guard is chasing the boat, there is a shot looking at Wilford Brimley. The perfect shadow of the camera can be seen since the light is directly behind the operator.

1 visible crew/equipment mistake - chronological order
Directed by: Ron Howard
Starring: Brian Dennehy, Steve Guttenberg, Hume Cronyn, Wilford Brimley, Don Ameche
Continuity mistake: Tawnee Welch massages Steve Guttenberg's right leg just after he bangs it. However, when they are talking his left leg mysteriously becomes the injured one.
Art Selwyn: Men should be explorers, no matter how old they are. I don't know about anybody else, but I'm going.
Trivia: Some of the cloud effects were created by dumping colored dyes in tanks of water which were then superimposed into the shot.
