May famed actor Martin Landau rest in peace. The Oscar-winning star sadly passed away on Saturday, July 15 from a heart attack. And now, his daughter, Susan Landau Finch, is remembering her late dad in an exclusive new interview with Closer Weekly.

The actor’s little girl opened up about the impact his movies had on his long and successful life and acting career. “He really just wanted to be in big movies,” Susie said of her dad before noting something special about his 1988 credit in Tucker: The Man and His Dream. “The depth he brought to that role transformed his career,” the 56-year-old shared.

In 1994, Martin won the best supporting actor Oscar for his performance in Ed Wood. “His down-and-out times helped him play that role,” Susie added. Throughout his 64-year-long stint in movies and television, Martin was also most known for his appearances in North by Northwest, Mission: Impossible, Without a Trace, The Evidence, Space: 1999, and more!

And his acting stemmed long after he stopped filming movies. Every day before his passing he would drive himself to the Actors Studio in LA to help teach up and coming actors his ways. “He never wanted to stop,” Susie told Closer. “They’d say, ‘Martin, you have to stop at 1,’ but he would keep going. He was just so inspired.”

Martin is missed more than ever by his family already. “You always knew you’d get something good with him,” Susie gushed. “In one second, he’d be deep, then he’d make you laugh. He had that sense that life wasn’t black and white, even though his favorite movies were.”
