Torv's co-star John Noble recently admitted that he expects the Fox sci-fi drama to conclude after a fifth season.
"People have been quoting [series co-creator] JJ [Abrams] for a while saying [that] four or five years is kind of enough," Torv told the Coventry Telegraph. "I tend to agree with him."
The actress added that she has no desire to "run [the series] into the ground".
"If you're doing a straight-up procedural series, I think you can go on, because you've got so many stand-alone episodes," she explained. "Whereas with our show it certainly feels like it's picked up the pace as well."
Torv also admitted that she is uncertain about the likelihood of a Fringe spinoff film, suggesting that the show would not work on the big screen.
"I feel like it's so intricate, it feels like an epic story now," she said. "I don't think it would be a very good film."
Fringe continues tomorrow night at 9/8c on Fox.
