Cut twice and currently without a team, Michael Sam is not giving up hope.

"I'm not afraid to continue on this journey trying to make an NFL team," says Sam in a video titled #IAmUnbroken. "I'm not going to let this discourage me. I'm not going to let this break me down."

The video is part of a series of spots promoting the new movie "Unbroken," a war-time epic directed by Angelina Jolie and based on a true story.

Along with other notable athletes and celebrities, Sam uses the video clip to assert his determination and persistence in reaching his dreams.

The video also discusses some of the challenges Sam has faced since coming out to the public earlier this year -- challenges that have not deterred him.

As the 2014 season nears its end, Sam would appear to face an uphill battle. Although he suited up in the preseason for the St. Louis Rams, he failed to make that team's regular-season roster.

Dallas signed him to its practice squad, but his stay was short-lived. Since his release from the Cowboys in October, Sam has yet to find a home in the NFL.

Maybe the offseason will bring an opportunity.
