Fast and Furious 7 wasn't the only film Paul Walker had in the works before his death. The 40-year-old actor, who died in a tragic car wreck on Saturday, Nov. 30, gave one of his last film performances in the movie Hours. The thriller is now in post-production, and set to be released in theaters on Dec. 13. 

In the Eric Heisserer-directed film, Walker played the role of Nolan, a father trying to keep his infant daughter alive in the wake of Hurricane Katrina. The film also stars Genesis Rodriguez, as his wife Abigail.

The film's backdrop isn't a stretch from what the Hollywood hunk has witnessed in real life. In 2010, Walker created the non-profit organization, Reach Out Worldwide, after experiencing firsthand another natural disaster -- the Haiti earthquake in January 2010.

"Actor/Producer Paul Walker saw a gap between the availability of skilled resources and the requirement for such personnel in post-disaster situations," reads a statement on his ROWW website. "Following the trip [to Haiti] he contacted a group of his friends to assist him in forming ROWW with the purpose of filling this unmet need."

Indeed, Walker -- in between red carpets and promoting his own projects -- always found time to give back to others. Some of his other relief efforts over the years have included helping victims from the 2010 Chile earthquake and the Oklahoma City tornado in June. On the day he died, Walker was attending a toy drive in Santa Clarita, Calif., to raise money for those who recently suffered from the Philippines Typhoon.
