Matthew McConaughey's 7-year-old son, Levi, had a lot of fun visiting his dad on the set of his upcoming Civil War movie, Free State of Jones, but he also learned an important lesson.
"He was there a lot," the 46-year-old actor told ET, adding that his son was first excited by all the classic machinery and props used in the movie. "He got to press the buttons to explode a lot of the things, or at least he thought it was him doing it."
However, upon being exposed to some of the tragedies that go with war, Levi had an honest moment with his father.
"They had made a bunch of dummies that looked very, very real," said McConaughey, discussing a battle scene from the film. "I stood beside him and for about a minute he just stared [at them]... He goes, 'Papai, I don't want to go to war.' I was like, ‘Yeah I hear you.’"
The actor also shared plans for his Father’s Day celebration with Levi and his two younger siblings, 6-year-old Vida and 3-year-old Livingston, admitting that he didn’t realize the holiday was coming up this weekend.
"I had to be reminded Father's Day is coming up," he revealed, adding, "But you're damn right I knew when Mother's Day was."
Free State of Jones is set to hit theaters on June 24.
