Sylvester Stallone slams producer again over 'Drago' spinoff

Hollywood star Sylvester Stallone has doubled down on his criticisms of the direction of the 'Rocky' franchise, expressing his frustration regarding the newly announced spinoff film 'Drago'.

The actor shared his disappointment in a post on Instagram Saturday.

Stallone does not call anybody out by name in his writing, the star mentions a "94-year-old producer", a description which would seem to be pointed at 'Rocky' series producer Irwin Winkler, reports 'Variety'.

According to 'Variety', Winkler, who is actually 91-years-old, has been a target of criticism for Stallone before.

"Another Heartbreaker, Just found this outa ONCE AGAIN, this PATHETIC 94 year old PRODUCER and HIS MORONIC USELESS VULTURE CHILDREN, Charles And David, are once again picking clean THE BONES of another wonderful character I created without even telling me," Stallone wrote.

"I APOLOGIZE to the FANS, I never wanted ROCKY characters to be exploited by these parasites."

Stallone also acknowledged his relationship with actor Dolph Lundgren, who portrays Soviet champion boxer Ivan Drago in 'Rocky IV' and 'Creed II'.

It is unclear if Lundgren is set to reprise his role in the 'Drago' spinoff.

"By the way, I have nothing but respect for Dolph but I wish HE had told me what was going on behind my back," Stallone concluded.

"Keep your REAL friends close."
