Tim McGraw says brutal toll of filming 'Yellowstone' prequel pushed him to edge: 'Wouldn't have survived'

Tim McGraw was pushed to the brink while filming Taylor Sheridan's Western drama "1883." 

The country music superstar revealed that the brutal production schedule left him questioning how much longer he could keep going. Between 14-hour shooting days, six-day workweeks and late-night flights for concert performances, McGraw said the grueling experience was unlike anything he and his wife, Faith Hill, had faced before.

"If it had gone on any longer, I probably wouldn't have survived, put it that way," McGraw told Esquire.
