Yes, the star of Ghostbusters - he was the real star, wasn't he? - as well as the Honey, I Shrunk the Kids franchise appeared alongside Hollywood actor, entrepreneur and gin salesman Reynolds for a 30-second-long commercial, to promote a new phone plan from Mint Mobile.
To be fair, when the mobile phone company is owned by Deadpool himself, you can expect a certain calibre of celebrity to tip up in the adverts.
Moranis appeared alongside Reynolds for a brief segment in a series of three adverts, and their meeting took place in a field, for whatever reason.
It's Covid-safe, at least.
Moranis began his career on Second City Television before hitting the big time in the 1980s in films like Strange Brew, Spaceballs and Little Shop of Horrors.
Then, in the 1990s, he starred alongside John Goodman in the bizarre live action version of The Flintstones, as well as Big Bully and Honey, We Shrunk Ourselves, which would turn out to be his last live action role - until now.
Speaking about the advert, Reynolds said: "Like many, I've missed seeing Rick in movies for the past decade, so I pretty much begged him to re-emerge for Mint.
"There's really no good reason for it except this year has been weird and I thought we could all use more Rick Moranis."
Well, that seems fair enough, really.
As for the piece itself, there's not that much revealed other than that Mint Mobile has an unlimited mobile plan, and Ryan Reynolds really likes Rick Moranis.
Incidentally, Moranis is coming out of his self-enforced hiatus pretty soon for yet another film in the Honey, I Shrunk series.
This time, it's just called Shrunk, and we don't actually know that much about it yet, other than that it focuses on the son of Moranis' character Wayne Szalinski, played by Josh Gad - who voiced Olaf from Frozen - as he follows in his dad's footsteps and shrinks his family.
The original director from the first film, Joe Johnston, is also returning to the fold for this next one.
The latest movie was announced in 2018, and principal photography was supposed to start in 2020, but - well - you know what happened at this point, don't you?
As of right this second, there is no word on when the production will start, as Disney has ceased production on all live-action feature films, so we'll have to wait a while yet for more Moranis.
