LOS ANGELES — Len Lesser, the veteran character actor best known for his scene-stealing role as Uncle Leo on "Seinfeld," died Wednesday. He was 88.

Lesser's family said in a statement that he died in Burbank, Calif., from cancer-related pneumonia.

"Heaven got a great comedian and actor today," his daughter, Michele, said in the statement. "The outpouring of sympathy we've already received has been amazing and is so greatly appreciated. Thank you to all the people who helped make my father's last journey special and surrounded with love."

His film credits included "Outlaw Josey Wales," "Kelly's Heroes," "Birdman of Alcatraz" and "Death Hunt." He most recently appeared on the TV drama "Castle."

"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
