The marathon will begin Sunday, April 13, at 6 a.m. Eastern time with the 1933 film "Broadway to Hollywood."
Other films in the marathon will include "A Family Affair" and "You're Only Young Once," the first two movies in the Andy Hardy series; "Babes on Broadway," one of Rooney's many pairings with Judy Garland"; and "The Human Comedy," for which Rooney earned an Oscar nomination for best actor.
The same day, the TCM Classic Film Festival in Los Angeles will feature a newly added screening of the 1944 Rooney film "National Velvet," to be followed by a conversation by Rooney's close friend and fellow screen star Margaret O'Brien.
TCM host Robert Osborne said in a statement, "Mickey Rooney was easily one of the most talented people in American show business. Actor, singer, dancer, musician — he did it all. And what's truly remarkable is that he did it so well for so long."
TCM also posted a short Rooney tribute video online.
