To be honest this doesn't surprise me. I am glad his sister said something and gave examples of what exactly her brother and other actors go through for a role. Most people think that acting is just getting in front of the camera and saying lines ala The West Wing, The Practice, or Law and Order. Some people don't even consider it a job. The truth is shooting schedules are grueling and brutal by nature. It is VERY RARE that a movie or TV episode shoots last more than 2-3 weeks.
Most TV episodes are shot over the course of a week with actors getting a script on Sunday, learning their lines on Sunday and Monday, rehearsing Tuesday and Wednesday and shooting Thursday and Friday and Saturday. And that is not including stunt/fighting rehearsal, makeup, costuming, and prosthetic fitting, and a bunch of other things that they have to do for the show.
The Lord of the Rings Trilogy and Avengers: Infinity War/Endgame are some examples of movies that took months to years to shoot. While in terms of TV the Arrowverse/Berlantiverse crossovers are the projects that come to mind when it comes to longer shoot times. If you want a good example of the type of toll an actor can face due to the shooting schedule of a TV show or movie I recommend you look up what happened to Stephen Amell after he finished Arrow and before he went on to Heels. It shed some much needed light on what actors can experience while working on a show or movie.
