Apollo 13 behind the scenes gags

Apollo 13

At the premiere of the film, director Ron Howard asked the audience to write down their impressions, and most people's comments on the film were very positive. One of them wrote in his afterthoughts: The astronauts in the film could not survive the accident-he obviously did not know that the film was adapted from real events.
This film is the one that Ron Howard directed the most.
In the commentary video, Jim Lovell's wife Marilyn Lovell praised Tom Hanks' performance, saying that he perfectly reproduced Lovell's actions.
It is true that Marilyn accidentally dropped the wedding ring into the sewer in the film-but in the end she managed to get the ring up.
The most famous line in the play "Houston, we've had a problem." (English: Houston, we've had a problem.) was actually said twice, the first time it was said by Sweigert, who was on duty at the time Jack Losma, the spacecraft correspondent, did not hear clearly, and asked him to repeat it. Sweigt hesitated a little, and Lovell repeated it for him.
Jim Lovell himself appeared at the end of the movie, and he played the captain of the USS Iwo Jima. Ron Howard originally wanted him to play a rear admiral, but Lovell insisted on playing the captain-he was a navy colonel when he retired, and the corresponding job happened to be captain, and the English-speaking navy colonel and captain happened to be the same. The same word (English: Captain). He described his role like this: "I was a colonel once, and a colonel for life." (I retired as a Captain; a Captain I will be.)
The image of the Saturn 5 launch vehicle in the film is completely computer generated, and no real image has been used. The final effect is so realistic that even Jim Lovell himself can’t tell the truth from the false-the first time he saw this During the scene, I felt strange, thinking that from where the film crew got the images that NASA had never made public.
John Cusack refused to play Fred Hayes in the film.
John Travolta refused to play Jim Lovell in the film.
Brad Pitt missed the film in order to star in "The Seven Deadly Sins".
Because the amphibious assault ship USS Iwo Jima was retired before the filming started, the amphibious assault ship USS New Orleans appeared in the film.
Jim Lovell is left-handed, but Tom Hanks, who plays him, refuses to write with his left hand in the film.
The film is the first film co-produced by NASA.
