Disney

This showed up while looking into the next Grid entry for First Turnings:

In October 1947, when the House Un-American Activities Committee (HUAC) started investigating whether communists had infiltrated Hollywood, the first day saw testimony from two well-known friendly witnesses: Ronald Reagan and Walt Disney. Both were staunchly opposed to communism and considered it a threat in the post-war era.

Reagan was a studio actor who had recently been elected president of the Screen Actors Guild. Disney was the head of a movie studio, but one that was still a few years away from its first live-action film. Whatever else they might have had in common, they ended up in front of the HUAC on that same day.  It seems reasonable that may have been where they first met. (A search on the subject leads largely to conspiracy theorists and coverage of a Disney exhibit at the Ronald Reagan library.)

Both men, while quite willing to acknowledge a communist threat, seem uneasy about how the Committee might handle it.  When Reagan is asked about possible solutions, he suggests democracy:

Mr. STRIPLING: Mr. Reagan, what is your feeling about what steps should be taken to rid the motion-picture industry of any Communist influences, if they are there? 

Mr. REAGAN: Well, sir . . . 99 percent of us are pretty well aware of what is going on, and I think within the bounds of our democratic rights, and never once stepping over the rights given us by democracy, we have done a pretty good job in our business of keeping those people’s activities curtailed. After all, we must recognize them at present as a political party. On that basis we have exposed their lies when we came across them, we have opposed their propaganda, and I can certainly testify that in the case of the Screen Actors Guild we have been eminently successful in preventing them from, with their usual tactics, trying to run a majority of an organization with a well organized minority. 

So that fundamentally I would say in opposing those people that the best thing to do is to make democracy work. 

His testimony ends in the same vein:
I never as a citizen want to see our country become urged, by either fear or resentment of this group, that we ever compromise with any of our democratic principles through that fear or resentment. I still think that democracy can do it.

Disney is less conciliatory, perhaps influenced by a bitter strike a few years earlier that makes up a significant part of his testimony. While open to more aggressive options, he still has concerns about what might be lost:

Mr. SMITH: There are presently pending before this committee two bills relative to outlawing the Communist Party. What thoughts have you as to whether or not those bills should be passed? 

Mr. DISNEY: Well, I don’t know as I qualify to speak on that. I feel if the thing can be proven un-American that it ought to be outlawed. I think in some way it should be done without interfering with the rights of the people. I think that will be done. I have that faith. Without interfering, I mean, with the good, American rights that we all have now, and we want to preserve.

However they came to know each other, it was just over 7 years later -  July 17, 1955 -  that Disney would unveil his grand theme park, Disneyland, with Ronald Reagan helping out as host for the festivities.
