Mark Frost: The co-creator of the show reprises his role as Cyril Pons (the man walking with the dog) from May the Giant Be with You (1990). His name appears in the end credits but isn't said out loud. In his first episode, his name was shown in an onscreen graphic but not in the end credits.
The episode is dedicated in Memory of Margaret Lanterman, the character, not to actress Catherine E. Coulson, who played the role. Instead, episode #1 is dedicated in Memory of this actress.
