The Todd Miller Apollo 13 documentary (which is phenomenal, it's entirely file footage but assembled better than most blockbusters) has these bits during launch/landing where they overlay the three astronaut's heart rates with the footage. My big takeaway from that was that they were incredibly unflappable, almost to an absurd degree.
I think you mean Apollo 11, Apollo 13 was the dramatization with Tom Hanks. Both excellent movies in their own ways.
Oh drat. Yes, you're 100% correct.

Not as good as For All Mankind (the 1989 documentary) IMO! Link: https://youtu.be/JD2W4CZbH9U?si=WvdYuLnoe49_tV0l
it's available on Criterion 4k disc too!
Not to take away from their achievement, but do we know if there were drugs involved?
Not for takeoff. Apollo astronauts used barbituates to help sleep, and scopolamine with dextroamphetamine during re-entry. Unsurprisingly the average HR during re-entry was rather higher than at launch! (source: https://space.stackexchange.com/a/31987 )
Gemini would likely have been similar, save for using Cyclizine during re-entry rather than scopolamine/dextroamphetamine.
