When speaking about when they first met, Seyfried readily admits, "We were both in bad relationships...[Thomas] never flirted, never disrespected his wife. That was another reason why I thought, later on, that I could marry him." She added that when they finally got together, "it was amazing. It felt healthy and freeing and clean. We can tell the story without any guilt" (via Style Caster).
Another person who gave a shout-out regarding his admirable character is his former Newsroom co-star, Olivia Munn. Referring to an incident where Seyfried said Sadoski "lost out on a job" because he stood up for a fellow actor, Munn wrote, "Extremely grateful for my friendship with this guy, his conviction, his dedication to standing up for what's right even if it comes at a cost" (via Indie Wire). We know he has a great reputation with his wife and colleagues. And per social media, we get the sense that he is dedicated to drawing awareness to world issues. Several recent posts on his personal Instagram profile show videos and photos bringing to light the current violence and disruption in Myanmar (via Instagram).
So while Sadoski might not have as bright of a spotlight as his spouse, it appears he is certainly making his presence known where it matters the most.
