Sammie Dell plays the role of Bart's son named Sam. He talked about taking on that role.

Dell said, "I was kind of a part of the hype of the first 'I Can Only Imagine'. I remember seeing it, and to kind of come in and do a sequel film is mind-boggling to be able to sit next to these two guys. To come in and play Sam is kind of like another aspect because I'm so used to hearing Mercy Me and Bart, but then to go under that level and go deeper into the family was a really cool experience."

Singer and Songwriter Tim Timmons is Millard's best friend and the co-writer of the song "Even If." Timmons has been living with an incurable cancer since being diagnosed in 2001. He shared with CBN News' Studio 5 how he is doing decades after the diagnosis.

Timmons said, "There's still tumors on my liver wearing out my heart, they say. But I was given five years to live 25 years ago and I... today, I woke up again. I got off a plane this morning, and I woke up again today. And then tomorrow if I wake up again, giddy up."

Actor Milo Ventimiglia portrays the role of Timmons and revealed what he did after being offered the role. 

"I was offered a movie called 'I Can Only Imagine 2' and I'm like, I should probably watch the first one. I like that. But I did it on the heels of reading this beautiful script, the roadmap that we have to make the second film that I'm like, wow, I should really watch the first film... And then it just keeps going. These breadcrumbs keep tumbling into a larger ball of awesomeness. And I get to meet and study and just become friends, close friends with Tim Timmons. And what a gift that is," said Ventimiglia.

Playing the role of Timmons arrived at a trying time for Ventimiglia with the loss of his house due to the destructive California wildfires.

"You're given this moment in your life where everything physically is taken from you. And in the same two weeks, everything is given to you with the birth of our first child, my daughter. I think these two diametrically opposed things just existing at the same time and then strangely mirroring just thematic concepts of the movie was like, crazy," Ventimiglia told CBN News' Studio 5. 

"Then even in the script, talking about God is in the fire. I'm like, 'I just experienced the fire.' And how you push through these moments and all of that is just a wonderful thing to be given as an artist, as a husband, as a father, as a friend. And it was exactly what I needed at the right time. I don't know if the performance would have been the same had I not lost my house in a fire, but you know what? We'll never know because it happened," he continued. 

"I Can Only Imagine 2" is in theaters nationwide on February 20th.
