Harvey Weinstein has given up any hope of getting out of prison on bail, his lawyers say, but still thinks he’ll win an appeal, which the ex-movie mogul wants to be “the Sistine Chapel of appeals.”

Weinstein’s legal reps began building his appeal in February, after the disgraced honcho was convicted on rape charges. But the appeal was delayed by the pandemic.

Now Weinstein’s attorney, Arthur Aidala of Aidala Bertuna & Kamins, tells Page Six he expects the appeal to be filed by the end of this year.

Weinstein just lost a bid to be released on $2 million bail pending appeal. “He’s come to grips with the reality of the situation,” Aidala told us.

But Weinstein is still “pretty optimistic — having lived through the trial and seen all the legal improprieties — that he’s going to be successful on appeal,” said the attorney, who has not seen Weinstein in person since March 12, but spoke to him by phone as recently as Friday.

He said Weinstein is expecting Aidala’s firm to “be Michelangelo” and “build the Sistine Chapel of appeals.”

As far as how Weinstein has adjusted to life behind bars at Wende Correctional Facility east of Buffalo, Aidala said, “I don’t think he would mind a change of scenery, but he’s hanging in.”

Harvey’s lawyers will argue there were issues with the judge as well as a juror. Weinstein is also being repped by the firm’s Imran Ansari.
