Williams, 63, was battling severe depression, at the time of his death and was secretly grappling with the onset of Parkinson’s disease.
He fretted about money, was trying to sell his expansive California estate and winery without much luck and was working almost around the clock on four films.
“Merry Friggin’ Christmas” was one of the four and the last he actually filmed, according to ET online.
It also stars Lauren Graham, Candice Bergen, Clark Duke and Joel McHale.
He also had filmed “Night at the Museum: Secret of the Tomb” in which he reprised his role as Teddy Roosevelt. In addition, he voiced a dog in the British animated comedy “Absolutely Anything.”

All three will be released posthumously.
Two other films were released earlier this year, “Boulevard,” a gritty drama that premiered at the Tribeca Film Festival and “The Angriest Man in Brooklyn,” a comedy-drama co-starring Mila Kunis.
In “Merry Friggin’ Christmas, Williams is a curmudgeonly father who is soured on life and estranged from his son Boyd Mitchler (McHale).
Boyd and his wife travel to meet his dreary father and his odd-ball relatives, but realizes once he gets there that he’s forgotten all his son’s gifts.
So Boyd hits the road with his father and younger brother in a bid to make an 8-hour round trip to Boyd’s house before sunrise. Needless to say, craziness ensues.
