If that's the case, get Jesse Hutch or Tyler Hoechlin to spite Grillo. Idk why Grillo is hatin on Jesse Hutch but as for Tyler, it probably has something to do with Tyler being Maltese/Swiss origin and possible jealousy. Refer to Bebe Rexha's tweets about Frank.
I agree with most of what you said except for the Rachel Zegler stuff and pro-immigrant. His parents are immigrants of Southern Italy. He hates open border policies and invasions. Frank Grillo blasted Rachel because of what Rachel did to Jenna Ortega. Remember, Frank was being promoted by Jenna Ortega because of Boss Level, Werewolves, Tulsa King...he owes Jenna a huge favour. Why else did he promote her new movies and that Netflix show she's on? I forgot the title.
Also, not because he is not a big star why they flew under the radar (refer to Hartley Sawyer incident), He is a bigger star than the people who got cancelled and never recovere. It's because of his PR team, Jenna Ortega, James Gunn, John Cena (yes, Frank dissed John "You can't see him"), etc...
Let's face facts. Him starring in Wolf Warrior 2 should have gotten him cancelled because that movie is a pro-China anti-America Propaganda movie. However, he is still rising.
I hate to say this but 2025 until who knows when, is gonna be the return of the Frank Grillo Era but as an action star and not a sex symbol anymore. Meaning, he will be everywhere and will be in our heads rent-free.
