The ‘Rain Man’ director was floored by Tom Cruise’s surprise on-set skill

Looking back 38 years after Rain Man hit theaters, director Barry Levinson says one thing about making the movie still surprises him: how naturally Tom Cruise could wing it on set alongside Dustin Hoffman. In a new conversation with People, Levinson said the actors often built moments between Charlie and Raymond on the fly.

“And the two of them were wonderful together, Dustin and Tom, because we had to do a lot of improvisational things as we went along, and Tom was not known for that, but was exceptionally good,” he said.

The road-movie structure gave them room to discover the brothers ’ rhythm scene by scene. As Charlie and Raymond crisscrossed the country, Levinson leaned into that freedom so their guarded, prickly bond could evolve into something more like family — and he credits the performances for making that shift feel unforced.

Cruise, off the cuff

Cruise’s improv chops didn’t start or end with Rain Man. On Risky Business, the script only said Joel would dance in his underwear. Cruise built the entire routine himself — sliding in socks, strumming a candlestick “guitar,” hopping on furniture — turning a throwaway beat into an era-defining scene.

There’s a famous on-the-spot save in Top Gun too: after forgetting a line opposite Kelly McGillis, Cruise stayed in character and kissed her. The unscripted move worked so well it made the final cut, a neat example of his instincts sharpening a moment rather than derailing it.

Rain Man’s run

In Rain Man, Cruise plays Charlie Babbitt, a grasping car dealer chasing a $3 million inheritance who initially treats his autistic savant brother Raymond (Hoffman) like a problem to solve. Over the cross-country trip, Charlie’s slick bravado cracks as the brothers’ connection deepens — the kind of gradual shift Levinson says was fueled by those improvised beats.

The movie didn’t just land emotionally; it dominated commercially and at the Oscars. Made for $25 million, Rain Man grossed more than $350 million worldwide, becoming the highest-grossing film of 1988. At the Academy Awards, it took home four trophies:

• Best Picture
• Best Director (Barry Levinson)
• Best Actor ( Dustin Hoffman)
• Best Original Screenplay
