The effects of the Vietnam War reverberated for years after it ended, both in the lives of the people who'd fought or lost loved ones and in our popular entertainment. One man forever changed by the war was Oliver Stone, the maverick director who served as an Army infantryman from 1967 to 1968 and subsequently made three movies set in 'Nam: Platoon (1986) won him a Best Director Oscar; Heaven & Earth (1993) fizzled with critics and audiences; but in between was Born on the Fourth of July (1989), a star-spangled Tom Cruise vehicle that earned Stone another Oscar and Cruise his first Best Actor nomination. Here are a dozen items of interest about this turning point in both men’s careers.

1. Al Pacino almost played Ron Kovic.

This was in 1978, when Oliver Stone and Ron Kovic first wrote the screenplay based on Kovic's 1976 book. William Friedkin (The Exorcist) was going to direct it; he dropped out and was replaced by TV director Dan Petrie; and then, less than a week before shooting was set to begin, the German financiers behind the project got cold feet and pulled out. Stone later said that while Pacino would have been great, he had qualms about the then-38-year-old actor being too old for the part. (Tom Cruise was 27 when he played the role.)

2. Kovic has a silent cameo.

He can be seen in the parade at the beginning of the film, playing the wheelchair-bound soldier who flinches at the sound of firecrackers.

3. Tom Cruise's casting hurt Charlie Sheen's feelings.

Charlie Sheen, who had starred in Stone's previous Vietnam blockbuster, Platoon, believed Stone was going to cast him in Born on the Fourth of July, too, and said (in 2011) that Stone had flat-out told him the part was his. When Cruise was cast instead, Sheen heard the news not from Stone but from his own brother, Emilio Estevez. Sheen said he was "hurt ... I wouldn't have cared if Oliver had called me personally, based on what we'd been through." Stone didn't respond to Sheen's claim, but news outlets in 1989 reported that Sean Penn and Nicolas Cage had also been considered for the role.

4. Oliver Stone considered (temporarily) paralyzing Cruise to play the part.

Stone found a nerve agent that would paralyze Cruise for a few days, and Cruise was open to the idea of using it. But the studio's insurance company—spoil sports—nixed it.

5. Cruise prepared for the role by using a wheelchair for a while.

Wanting to relate to Kovic's experience as much as possible, Cruise got himself a wheelchair and role-played for weeks, even staying "in character" when doing media interviews and going to studio meetings. He also accompanied Kovic on public outings to see how a pair of paraplegics were treated. (They were once asked to leave a store because their wheelchairs were leaving marks on the floor.)

6. Vietnam was actually the Philippines and Long Island was Dallas.

Shooting on location in Vietnam wasn't an option (U.S.-Vietnamese relations were still a bit frosty), so Stone used the Philippines as a stand-in. (That's where the Mexico scenes were shot, too.) As for the scenes set in Ron's Long Island hometown and at the Republican convention in Miami, those were all shot in Dallas—not far from places Stone would soon revisit to make JFK.

7. Kovic was so moved by the film that he gave Cruise his Bronze Star.

Kovic had been skeptical when Cruise was first cast, but was soon won over by the actor's commitment to the role and his sincerity. When the film was finished, Kovic gave Cruise his Bronze Star as a token of his admiration.

8. Universal paid $500,000 to make one scene bigger.

The film ends at the 1976 Democratic National Convention, with Ron about to give a speech. After seeing a rough cut of the movie, Universal ordered that the scene be re-shot with a larger crowd—6000 extras instead of the 600 Stone had used. It cost $500,000, but was accomplished in one day at L.A.'s Forum arena.

9. Stone ended up apologizing to a police department for using some creative license.

In the film, Ron is shown being beaten up and arrested at an anti-war demonstration in Syracuse, New York. In real life, Kovic had not attended that event, which was peaceful and was not broken up by police (though others were; Stone had consolidated several incidents into one). After complaints from the Syracuse Police Department, Stone reportedly sent a letter of apology in March 1990.

10. Kovic's visit to the family of the soldier he killed was fictional.

One of the most emotional sequences in the film is when Kovic travels to Georgia to meet the parents and widow of the soldier he accidentally killed in Vietnam. In real life, though Kovic expressed his remorse to the family publicly in his book, he never met them. Apologizing via a memoir isn't very cinematic, though, so Stone and Kovic invented a face-to-face scene.

11. Stone and Cruise both agreed to work on the film for next to nothing.

The director and star were both so enthusiastic about the film that they agreed to keep production costs low by forgoing their usual high salaries (Cruise's especially) in exchange for a percentage of the profits. It paid off. The film cost about $18 million to make and grossed $161 million worldwide.

12. Born of the Fourth of July's television debut was delayed by a real war.

As you can imagine, it took a lot of work to make Born on the Fourth of July suitable for broadcast on network television. CBS had a version ready to air in early 1991, barely a year after the film's theatrical debut, but called it off because of the impending Persian Gulf War. It finally aired in January 1992.
