I just finished watching Clint Eastwood’s new movie called El Macho. Love Clint.

Clint Eastwood is 91 years old headlining a film. This has to be some kind of record for Althea advanced age of a lead performer. George Burns was only around 80.

Who is the oldest person to headline a TV show?

From June, 2010 to June,2015, Betty White headlined 'Hot in Cleveland' from ages 88 to 93. I think she may be the oldest regular performer on a TV series.

Betty White also hosted a Candid Camera like show Off Their Rockers that ran on NBC for two seasons and switched to Lifetime for one more season.

Was that more of an ensemble show, or did Betty really lead it with the other ladies being more supporting?

I don't know if this is a definitive answer, but Judd Hirsch was the lead in the ensemble cast of the CBS sitcom Superior Donuts, which lasted for two seasons from 2017-18. Judd Hirsch was born in 1935, so he would've been at the very least, 82 years old when Superior Donuts premiered.

I know that, a little more recently, Alan Arkin co-starred alongside Michael Douglas on Netflix's "The Kominsky Method" from 2018-19.

He was 84-85 at filming.
