Larry Miller – a familiar face from his appearances on Curb Your Enthusiasm, Seinfeld, The Nutty Professor
and several Garry Marshall-directed movies (Princess Diaries, Runaway Bride, Valentine's Day, New Year's Eve
) – has recovered from a life-threatening brain injury.
The actor, 58, fell and hit his head
last April. He had just finished a podcast with comedian Adam Carolla when he lost his footing and hit the back of his head on a sidewalk.
His spokesman now reveals that Miller, a married father of two, had gone into a coma and was then put on life support at UCLA Medical Center for one month.
"He was hovering between life and death," says his spokesman, Michael Hansen. "It's a miracle he woke up. ... He's lucky to be alive."
After Miller regained consciousness, he began a long recovery process to re-master basic cognitive functions.
"He had to work on some issues regarding brain connectivity," says Hansen.
Now expected to make a full recovery, Miller is back at work on his podcast series, This Week with Larry Miller
, which resumes Jan. 9.
"I'm very thankful to have recovered from a traumatic brain injury so quickly," Miller tells PEOPLE.
