Carter played the costumed hero in a television series that began on ABC in 1974 and later aired on CBS from 1977 to 1979.
"I was really interested [in the project] and I was really happy that they were going to redo it, because the [Wonder Woman] story is a great story and I think it needs to be retold. It needs to go to another generation of people," she told Zap2it.
NBC last month declined to pick up the pilot, which starred Adrianne Palicki as Wonder Woman. NBC Entertainment chairman Robert Greenblatt later explained that the project "didn't seem to fit in with" the network's new schedule.
"I was disappointed that it didn't work out, and I don't have a clue as to why it didn't work out [or] what the problems were," said Carter. "But you never know, things can still get resurrected or retooled, so I haven't given up [hope]."
The actress also confirmed that she was planning to make a cameo appearance in Wonder Woman if it had gone to series.
"I was on the road at the time of shooting [the pilot]," she explained. "I couldn't get there. The schedules didn't line up. But I fully expected it to be picked up, and then mostly likely I would have done something."
