First time Acting nominee most likely to return?

Yeah, I'd say Driver is definitely the most likely. More or less guaranteed that he gets another one at some point. He's very well-liked, just popular enough, and continues to make a career out of largely working with renowned filmmakers in critically-acclaimed projects. I mean, he's already pegged as an early contender next year with The Report premiering to all sorts of acclaim. It's hard to believe he won't be nominated again, and I could definitely see a win for him in the future depending on how things shape out. That BlacKkKlansman nod is the definition of "welcome to the club" recognition. 

Colman and King would be the next two most likely, with basically an equal shot. Obviously King mostly works in TV, and Colman mostly does British projects that go under-seen by U.S. audiences, but they both seem likely to take more roles in the future that will have Academy appeal, so I certainly think that either or both of them will continue to be in awards conversations down the line. 

Malek I also think has a decent enough shot at becoming a repeat nominee, but it all depends on the types of roles he takes. But considering his relative youth and the fact that he's already had a ton of awards success across media, I wouldn't bet against him. 

With Gaga, how much she'll continue to act is the big question mark. I'd be surprised if she doesn't have at least more musical nominations in the future, though. I also wouldn't bet on Elliott or Grant, both have been pretty under-the-radar for each of their careers until now, and I think these nominations may be the most "overdue" recognition in store for them. Again, with the right roles either could return, but I'm not counting on it.  

1. Adam Driver - I agree with everyone else that he's the most likely to make it back especially after breaking through with his first nomination.

2. Olivia Colman - I agree with stephen about the Judi Dench comparisons. British actress in a leading role as the Queen of England plus critics favorite only to lose to an American actress, and then comeback and win in supporting and get multiple nominations later on.

3. Regina King - Mostly doing television, but I think she'll get more offers again in film. Whether those film roles will be worthy of another nomination is hard to say though. Like I wouldn't have guessed that Octavia Spencer would be nominated twice more and be on the radar already for next year after The Help. Just given her age and the fact that she was a black character actress, I thought it would be difficult for her to be nominated again, but luckily she's proven me wrong. So hopefully King will be more like Spencer and not like a Halle Berry.

4. Richard E. Grant - The way he's charmed everyone this awards season, and the fact that I see some people frustrated that Ali is going to win his second for Green Book makes me think that Grant could have another nomination in him possibly a win similar to when Richard Jenkins was nominated for The Stranger and jumped to the top of casting lists and got another nomination with The Shape of Water. Plus, depending on what his role is in Star Wars: Episode IX, he could get a lot of raves for that too which should help him stay in people's minds when they're looking for an actor for a juicy role that he could play.

5. Rami Malek - Stephen is correct that Malek would be halfway to an EGOT if he wins, and correct again that sometimes after what the public might think is a bad win, voters don't and dig in even harder to prove that someone or something wasn't a bad win. I'm not entirely sure though. He and Bohemian Rhapsody keep exceeding what I originally thought would happen, but after seeing BR, I'm thinking that maybe I was wrong before in how talented I thought he was. So I feel that he could be a one and done winner as he likely won't ever get another role like Freddie Mercury again. He's proven me wrong so far though.

6. Sam Elliott - I hope he'll come back, but given his age and the fact that I think he makes it look too easy for what he does, I'm not sure he'll get the opportunity again. Never say never though.

7. Lady Gaga - I think she'll continue to keep acting, but similar to Malek, I'm not sure that she'll find the right role and timing again. Plus, for A Star Is Born, I think that the bar was lowered, but the next time it won't be. However, unlike Malek, I actually think she has a lot of promise, so you never know.

8. Marina de Tavira - Probably not. She's getting more exposure, but so far I haven't heard that anyone is dying to work with her like sometimes you'll see during awards season especially a relative newcomer.

9. Yalitza Aparicio - Probably not either. I don't even know if she wants to continue acting. If she does, I think it's going to be incredibly difficult for her to find good roles that could lead to another nomination. I look at other newcomers that got nominated like Catalina Sandino Moreno or Quvenzhané Wallis who were more conventionally attractive, no offense to Aparicio who I think is pretty, and they've struggled trying to find another baity role.

Unlikely. Cotillard was young and a goddess and spoke some English. Aparicio speaks 0 English and de Tavira is way beyond that age.
