Patti Davis and Primary Wave Entertainment are producing the project, reported Variety.
Zak Knutson, best known for Film 4's "Milius," is directing the documentary.
"This is an honest, loving and truly behind-the-scenes invitation into the Reagans' lifestyle in a simpler time prior to their being cloistered by Secret Service and White House gates," the producers said.
The private footage offers a never-before-seen look at Reagan's family on vacations.
Reagan served as president of the Screen Actors Guild between 1947 and 1952 and again in 1959-60. He made his foray into politics in 1966 when he won the California governorship over incumbent Democrat Edmund G Brown and was re-elected in 1970.
