The two leads met on the set and became fast friends. Holden and Ford were actually less than two years apart in age, and they both were fairly new to the movie business. Ford remembered, “I liked him immediately, and we came to really care about one another, friend for life.” In fact, Ford kept in contact with Holden up until his death. After Texas, they did one more film together called The Man From Colorado.

Director George Marshall preferred using the actors, rather than stuntmen, for action sequences. Unfortunately, it wasn’t always safe, including when approximately five hundred cattle were used for a stampede scene. “It felt like an earthquake with all those cattle moving around us,” Ford said. When the animals changed course unexpectantly, a cameraman ended up in harm's way. Ford came to the rescue though. He lifted the crew member onto his horse and got away from the danger. Another time, Marshall used real bullets in order to get authentic scared reactions from Ford and Holden.

Like her co-stars, Claire Trevor didn’t escape the bumps and bruises that went along with making Texas. She got dragged across the dirt in one scene and endured traveling on a rickety wagon in other scenes. Fellow actor William Gould said, "A grand sport she is and one of the best actresses in town for my money." Trevor was gifted a saddle during the production, but it was heavy enough that she had a hard time lifting it.

Director George Marshall and Ford continued their relationship after Texas, working together on seven more films. “I feel that laughs have a rightful place in Westerns,” Marshall said. “People do not go to the theaters to read drab history books, but to be entertained.”
