On Thursday, Neeson appeared on Bravo's Watch What Happens Live to share the upsetting information he thought should have been included.
"We got hundreds – maybe a couple thousand – sympathy cards, emails and stuff from all over the world, especially America," Neeson told host Andy Cohen. "Not one from that ski resort."
The actor is referring to the resort where Richardson sustained a head injury resulting in the epidural hematoma that took her life. While this detail was omitted from Neeson's talk with 60 Minutes, the 61-year-old actor was happy with the interview overall.
