The love scene between Matthew Modine and Daphine Zuniga was almost to the point of controversy between the studio and Director Thom Eberhardt. The studio wanted a more "steamier" love scene between the two and spent an entire Saturday afternoon which lasted four hours reshooting the sequence much to Eberhardt and Zuniga's misery. In editing, they tried endlessly to make the scene work cutting, trimming and massaging it to make fit the film tonewise. The studio previewed the film with this scene one time and Jeffery Katzenberg the then CEO of Disney, was not happy with the scene and agreed with Eberhardt to cut it out because it did not work.
The scene where Daphine Zuniga and Matthew Modine greet at the bar was filled with tension. The reason was due to their dialog and Director Thom Eberhardt said to them "If you're uncomfortable with the dialog, then come up with something different". He had left for a moment and then when he came back both Zuniga and Modine were saying something different but both wanted to stick with they wanted to say and eventually, with the help of Ross Fanger, who worked with Disney's CEO Jeffery Katzenberg got the situation resolved and the actors stuck to the dialog as written in the end despite boring it was.

When they previewed the film with this version of the scene, two girls who were sitting behind Eberhardt in the theater and one of them said "I Knew She Was Going To Be A Bitch." In the end, Eberhardt was really happy with the final version that Zuniga had played because she had played it better.
It was Alice Carter's idea to wear a gas mask in the Gross Anatomy lab which Director Thom Eberhardt loved but mostly dude to the Frommaldahyde that was overpowering the room to the point that Daphine Zuniga would stand next to the door to get air.
The scene where Matthew Modine and Daphine Zuniga are talking on the porch in front of Modine's parents house was an all night shoot and it was an urgent final shot by Director Thom Eberhardt because sun was just starting to come up and was really happy that it took only one take to get it.
Director Thom Eberhardt won a bet between him and Producer Debra Hill for the scene where Matthew Modine and Daphine Zuniga are in the Anatomy lab together goofing around. Hill bet that the scene would never make the final cut of the film and Eberhardt knew that it would because the movie was already very long and there was alot scenes were due to be cut for pace and time. Eberhardt won twenty dollars from her.
The music department insisted that they use a song by the Beastie Boys which was very expensive against the wishes of Director Thom Eberhardt.

The Doris Day song that play in the background during the scene where Carter gives birth in the cafe.
The scene where Alice Carter is about to have her baby, the props department brought in a fake, rubber baby which would bounce on the floor if had fallen. Director Thom Eberhardt felt that even with lubing it up and everything it wouldn't make the scene work, but Matthew Modine felt that it really would work and in the end it did work without showing much of the baby as possible. Eberhardt was very happy in the end.
