The two are reprising their roles as Dr Alan Grant and Dr Ian Malcolm in the forthcoming Jurassic World: Dominion, and have been filming once more after production resumed following a Covid-related hiatus.
It looks like they've been able to enjoy some downtime together, with Neill sharing a series of Twitter videos showing him having a 'jam with Jeff'.
In one, they marked their 'reunion' by treating us to a rendition of classic tune 'I Remember You' - previously sung by the likes of Nat King Cole and Doris Day.
"This apropos to our reunion," says Goldblum, who is wearing dark sunglasses and a beret, to his co-star.
In a second clip, Neill explains that Goldblum 'flatly refuses to rehearse', meaning what we see is improvised and off-the-cuff.
"Every time is the first time," he tweeted, sharing their take on Kurt Weill's 'September Song'.
When filming resumed for the new Jurassic Park instalment, Universal decided not to send the film's first unit crew to Malta as planned, after the Maltese islands faced new outbreaks of the virus.
Instead, production sent its second unit instead, with a Universal spokesperson saying: "Jurassic World: Dominion will have a significant presence in Malta with a second unit crew shooting there from the end of August through to September.
"Working with an abundance of caution as we have done throughout this production, first unit will no longer shoot in Malta to keep our presence on the ground to a minimum.
"We'd like to thank the Maltese Government and Film Commission for all their support and we look forward to a successful shoot in this beautiful country."
Production on Jurassic World: Dominion was put on hiatus on 13 March, 10 days before the UK officially went into lockdown - but resumed in July.
When filming fired up again, Goldblum spoke about the precautions the studio has been taking to keep crew and cast safe - saying they are being quarantined in a 'bubble'.
Speaking to Entertainment Tonight, he said: "We're headed, in about a week and a half, all of us, over to England, where there are protocols galore.
"We're going to be very safe, I think. And we're going to shoot Jurassic World... They gave us 109 pages. They invested all their heart and soul, and a lot of money, into making sure that we're safe.
"I won't bore you with the details, but we're all going to be quarantined in a kind of a bubble, all the crew and all the cast. And testing and everything... We know it's a risky time, but we feel it's good.
"Sam Neill's there and Laura Dern and Chris Pratt and Bryce Dallas Howard; Colin Trevorrow's directing, and there are gonna be some dinosaurs."
