As I recall in the 1995 film Apolllo 13, the mission was threatened on top
of everything else by a typhoon heading towards their planned splashdown site.

They had a nice color satellite photo of the typhoon in the film, which I
don't think they did in 1970 and the extensive IMDB Goofs section on
Apollo 13 confirms:

"Anachronisms: The controller giving the typhoon prediction for the landing area can be seen holding a full color satellite picture of the region. There were no color satellite pictures at the time - especially not in (near) real time."

In a related item, David S. F. Portree has a new piece on what might
have happened if Apollo 11 had to abort its LM landing just above the
lunar surface inhis Beyond Apollo blog site here:
