Moranis is beloved by many fans for his roles in blockbuster movies like "Ghostbusters," "Spaceballs" and "Honey I Shrunk the Kids" despite putting acting aside in the late 1990s to focus on raising his children.
Chris Evans, who portrays Captain America in the Marvel movie franchise, wrote on Twitter: "My blood is boiling."
My blood is boiling. Find this man. You don’t touch Rick Moranis. https://t.co/VXBbTjdDwa

Evans' fellow Marvel superhero Ryan Reynolds, who plays Deadpool in the film series, expressed his relief that Moranis was okay.
Should have known not to subject Rick to the year 2020. Glad to hear he’s okay.

Josh Gad, who voices the character "Olaf" in Disney's Frozen, wished Moranis a "speedy recovery."
The rage I am feeling right now is beyond words. Who does this? What psychopath does something like this to a man in his 60’s. Speedy recovery my friend. 🙏🙏 https://t.co/u87CizhfHc

Sam Witwer, who played Mr. Hyde in ABC's Once Upon a Time, simply wished 2020, a year that has already seen so much negativity, was over.
Rick Moranis.

Would you kindly quit, 2020?
Finally, maybe the most flattering reaction came from ABC's The Goldbergs creator, Adam F. Goldberg, who described Moranis as "the most important person in our country."
The most important person in our country has been sent to the hospital today. As his biggest fan and supporter, I send Rick Moranis all the good vibes in my body. The country is united. You deserve better. #JusticeForMoranis

As for the investigation into the attack, police have yet to make an arrest.
Friday afternoon they released a clearer image of the suspect.

The attack happened just a few blocks from the apartment building where Moranis' character, Louis Tully, lived in "Ghostbusters."
The attacker continued walking north after throwing the punch.
Moranis hurt his head, back and hip in the attack but was able to take himself to the hospital, and later, to the police station to report the incident.
Moranis' representative Troy Bailey said in a written statement Friday: "Rick Moranis was assaulted on the Upper West Side yesterday. He is fine but grateful for everyone's thoughts and well wishes."
Anyone with information in regard to this incident is asked to call the NYPD's Crime Stoppers Hotline at 1-800-577-TIPS (8477) or for Spanish, 1-888-57-PISTA (74782).
