'Love And Mercy': WATCH John Cusack, Paul Dano In Brian Wilson/Beach Boy's Movie Clip!

Lionsgate Home Entertainment is taking the musical journey of Love & Mercy on Blu-Ray and DVD. Before the official September release date, check out this behind-the-scenes clip, featuring Paul Dano and John Cusack as they both portray the co-founder of the Beach Boys, Brian Wilson.

As we previously mentioned, Love & Mercy follows the tortured musical genius as audiences get a glimpse into the height of Wilson's career in the 1960s (the younger version played by There Will Be Blood actor Paul Dano). Then we witness the lows of his life in the 1980s (the older version played by Con Air actor John Cusack). If you remember the fifth season finale of The Walking Dead, you heard the Love & Mercy song covered by Gazelle Twin as the walkers shambled back into the vans.

In an interview with Screen Rant, Dano discussed portraying a real-life legend on the big screen, "I spent several months sort of working on it on my own before I met Brian - just sort of the research, the music, learning to play it, learning to sing it. I just wanted some time for my imagination to do its thing, and I do think Brian was different in the '60s than he is now. And I also just didn't want to go near mimicry for Brian. He's too sort of honest, you know, for that. He's just too sort of open and raw, so it was important for me to kind of get some time in by myself with the imaginary Brian. And then to meet him, he's got such a strong presence and spirit. Being in the room with him, you get something right away. To get to talk with him about music and geek out about being in the studio, I mean that was pretty great."

Check out this behind-the-scenes clip as director Bill Pohlad discusses Brian's life in the 80's and why how he thought of the Say Anything actor for the role of "Brian-Future."

According to USA Today, the musical biopic is currently available on digital HD platforms.

Love & Mercy will be available on Blu-ray and DVD September 15.
