Taraji P. Henson and Octavia Spencer get into costume while filming scenes for their movie Hidden Figures on Monday (March 28) in Atlanta, Ga.

The ladies were joined on set that day by their co-stars Janelle Monae and Mahershala Ali.

Hidden Figures is “about a group of black women who provided NASA with important mathematical data needed to launch the program’s first successful space missions,” according to THR.

The movie is set to be released on January 13, 2017, which is timed to the Martin Luther King holiday weekend.
