What may have Fastexybeen a planned "Scarface" reunion will have to wait another day.

At Sunday night's Oscars, Al Pacino alone presented the award for best picture — an honor that would go to the atomic bomb epic "Oppenheimer" — though the award show previously shared with media that his former co-star Michelle Pfeiffer was also set to be a presenter.

A rep for Pfeiffer told USA TODAY the actress wasn't able to attend due to a scheduling conflict and the award show was made aware last week.

USA TODAY has reached out to the Academy Awards for comment.

The Academy Awards never publicly confirmed the reunion in honor of the 1983 film. On Sunday, a presenter introduced Pacino by highlighting the 50th anniversary of "The Godfather," which was released 52 years ago this month. For the actual 50th anniversary in 2022, Pacino appeared at the Oscars on stage with Robert De Niro, who played Vito Corleone in the sequel, and director Frances Ford Coppola.

Pacino played Tony Montano in "Scarface" opposite Pfeiffer's Elvira Hancock, his on-screen wife. The actor, 83, played Michael Corleone in "The Godfather" and its sequels, 1974's "The Godfather Part II" and 1990's "The Godfather Part III."

Pacino did manage to present the award solo, though with a bit of a hitch. The actor sparked confusion, and lots of memes, with the unexpectedly casual way he announced "Oppenheimer" had won best picture.

The honor is traditionally revealed after a dramatic buildup sometimes accompanied by a drumroll for added effect. Instead, Pacino quickly opened the envelope and immediately blurted out "Oppenheimer" without preceding the film's title with the traditional "and the Oscar goes to." He also did not read the names of any of the other best picture nominees.

"Ten wonderful films were nominated, but only one will take the award for best picture," Pacino said. "And I have to go to the envelope for that, and I will. Here it comes. And my eyes see 'Oppenheimer.'"
