Seventy-seven-year-old Jim Walpole of Defiance fell Thursday in Toronto while on a trans-Canadian trip.
Walpole tells the Toronto Star that Malkovich, who was appearing at a local theater, applied pressure to slow the bleeding until medics arrived. The injury required 10 stitches.
Ben Quinn, whose family owns a restaurant nearby, held Walpole's head. He said by phone Monday that Malkovich "had everything under control" quickly, didn't want attention and called later to check on Walpole.
A message seeking an update was left for Walpole on Monday. Representatives for Malkovich did not immediately respond to messages seeking comment.
