Jeff Goldblum "had a vigorous conversation" with David Cronenberg in an attempt to change the ending of 'The Fly'.

The 72-year-old actor starred in the 1986 body horror as eccentric scientist Seth Brundle - who begins turning into a fly when the insect enters his teleportation machine - but was unhappy with the director's ending to the film that saw Brundle act violently towards his love interest Ronnie Quaife (Geena Davis) and their unborn child.

Speaking on the 'Smartless' podcast, Jeff said: "I had a vigorous conversation with (Cronenberg) about the ending. There was an ending which painted me, retroactively, in a villainous (way) - even though, I try to kill her at the end and meld all three of us."

Jeff admits that he became a "passionate protector" of his alter ego and didn't want Ronnie to end up with his love rival Stathis Borans (John Getz).

The 'Jurassic Park' star said: "By that time, I was such an advocate and passionate protector of my character, I was possessive. I didn't want (Veronica) to wind up with (Stathis). I said (to Cronenberg), 'Wait a minute!' Who was I to talk to him about that? But, as it turns out, it wound up ending kind of like that."

Although they disagreed with some elements of the plot, Goldblum had nothing but good things to say about his experience collaborating with the 'Dead Ringers' director.

The 'Independence Day' actor said: "He, even though he makes those wild movies, is a very buttoned-up, sweet Canadian. Civil, polite, delightful, smart, intellectual artist - who marches to his own drum, of course."

Jeff revealed that it took five hours to apply the necessary makeup and prosthetics for his depiction of an insect in the film but thinks the "passionate" experience was worth the time.

He said: "It was a very arduous, but lovely, passionate experience."

Meanwhile, Goldblum admitted last year that his time in the 'Jurassic Park' franchise is over after playing the role of Dr. Ian Malcolm in four of the films.

He told Total Film: "I think Ian Malcolm may have ridden off into the sunset. Maybe."

Jeff did express his excitement to see the next entry in the franchise, 'Jurassic World Rebirth', which stars Scarlett Johansson and his 'Wicked' co-star Jonathan Bailey and is due for release in cinemas in July.

He said: "This next one - my friend Scarlett Johansson and my new friend Jonathan Bailey from 'Wicked', I think, are taking up the reins. And I can't wait to see what they do. I think that's a good idea."
