Okay that might be a bit specific, but consider any actor you would like talk or rave about.

I am a big Ryan Gosling fan, under the usually calm exterior are deep emotions, and I've watched most of his films from; The Slaughter Rule(where he has to deal with a predatory football coach), through several great love stories like La La Land and The Notebook, troubled love stories like Blue Valentine and All Good Things(with another fav actor Kirsten Dunst, Melancholia by von Trier), plus of course Blade Runner 2049 and First Man(latter not seen yet). 

But the one I want to mention is Lars and the Real Girl. He plays a rather socially awkward young man, who is being pestered by his sister in law to get a girlfriend. He starts a romantic relationship with a sex doll(sounds like a Howard story), I won't give away much more, but the story says a lot about relationships, growing up, the reasons for his reluctance to make friends and the humanity of the town where he lives.  

"Leonard researches citations for Sheldon and Amy's paper. He finds a Russian paper that basically discredits super-asymmetry. Bernadette tries to beat Howard and Raj at Fortnite, and recruits help from Denise." - info is not confirmed. Taken from a post by Kev0821 on the other forum.

But if its true, I'm happy with this development. I don't think Amy should be shoe-horned into Sheldon's future accomplishments. It's bad enough that we have to hear every episode how there's something else that he credits to her.

Spoilers taken off wiki.

The plot revolves around Sheldon deciding to try and bond with his in-laws. Holy-boring-Frippin-Crappola! 

Sheldon fails to bond with Larry Fowler, who likes Howard’s magic tricks. He has better luck with Mrs Fowler when they talk about Amy. Amy used Sheldon as an excuse not to spend time with her mother and so Mrs Fowler realizes she’s been angry at Sheldon for no reason all this time. And they bond over their hatred of Amy and her dad putting ketchup on eggs. Amy’s mom tells Sheldon how can he defend Amy when she’s thrown him under the bus and he says she’s his wife and he loves her and if he can forgive her putting ketchup on eggs he can forgive her this. Yawn-a-flippin-tastic! How boring. (IS ANYONE ELSE SICK OF THEM CONTINUALLY UNDERLINING SHELDON'S AFFECTION FOR AMY? geez give it a rest already!!) So Sheldon decides he likes Mrs Fowler. 

Meanwhile, Raj and Anu are planning to sleep together for the first time and Raj gets so stressed out that he relapses back into selective mutism.
