However, from time to time, Lisa will see one of Patrick's movies come across the television, bringing her back to memories of him.

"Here and there, it kind of catches me unaware and I always have my favorite parts," she recalled. "I always cry in the same three places in Ghost. I always love him falling out of the back of the airplane in Point Break, going, ‘Adios, amigo,' because that's him. That's so quintessential Patrick."

Lisa even hears Patrick in her thoughts from time to time, encouraging her as he once had.

"His voice is in my head. He comments on what I'm doing," the One Last Dance actress confessed. "When I need a bolstering up or something's going on, I can ask him in my head, and I hear exactly what he's saying, which is generally, ‘Come on, girl, get real.'"

These days, Lisa is honoring the Powder Blue star's memory by becoming an advocate for the Pancreatic Cancer Action Network.

"I still care and I know how tough Patrick's and my journey was with this," she told host Hoda Kotb. "Cancer may have taken him, but it didn't beat him. And I'm continuing his fight for him."
