I think it has to be Rob Reiner because his father, Carl Reiner, was also a really big name that could stop any story about pedophilia even when Rob Reiner may not have been able to.
Rob Reiner and John Travolta seem like a “good candidates”.... others named such as Tom Hanks, Charlie Sheen, Tom Cruise, Brad Pitt, Robert Downey Jr., Sean Penn.... were too young in 1985-87, not yet “A-list” and not with any power to threaten or stop any revelations in that era, so far as I can tell...... John Travolta?? He was definitely “A-List” before the mid-1980s...... so Rob Reiner or John Travolta????? who knows......???? Travolta seems a lot more “revered” by millions worldwide than Rob Reiner ever was, although I certainly never revered either of them....... but they may fit the tease......
Gary Marshall was pretty powerful back then too and his sister was married to Rob Reiner who adopted her daughter. They divorced in the early 80s
