'Star Trek' actress Nichelle Nichols talks about show's 45th anniversary and new special 'Trek Nation'

"Star Trek" fans are waiting anxiously for a new documentary to premier tonight on the Science Channel called "Trek Nation."

It's the story of show creator Gene Roddenberry's son, Rod, as he tries to understand who his father was and the impact Star Trek has had on fans.

This morning on American Morning, Carol and Christine talk with Nichelle Nichols, who played Lieutenant Uhura on the original "Star Trek" series and was interviewed as part of the documentary. She talked about the show's 45th anniversary and the legacy of the show.

Producers had so much material from putting together "Trek Nation that they're publishing a web series with all the extra interviews and cool material that didn't make it into the final show. You can check the videos out on TrekNation's Youtube page here.
