The Monster Bros are voiced by series regulars Ben Diskin (Boris), Piotr Michael (Fearless Leader) and Rachel Butera (Natasha).
Ben Giroux, the voice of the Newsie, co-created and directed the 2017 comedy viral video sensation "Back to the 90s."
London's Big Ben clock tower, all 315 feet of it, was completed in 1859.
Bullwinkle's childhood doctor, Dr. Oldman, is voiced in flashback by Brad Norman, who is also the voice of Bullwinkle.
Rocky later made Bullwinkle write "Don't Eat That" on the back of his hand as a reminder.
