Oof. Yeah, good call, Luke. 

Mark Hamill likely will have plenty of lines in the upcoming Star Wars installment, which we now know is titled The Last Jedi, and that will be a nice change of pace from the zero words Luke uttered in the final moments of 2015's The Force Awakens

The silent Skywalker was all part of the script, but, in funny contrast, there was a line in the first Star Wars film Hamill hated so much, he "begged" George Lucas to cut it. 

Heat Vision recently discovered an old interview Hamill did on The Tonight Show in 1977, not long after A New Hope was released, where the youthful actor tells host Johnny Carson there was a piece of dialogue just too abhorrent to speak in the screenplay.

His pleading must have worked as the line is not in the film, but it was so bad, the snippet was ingrained in his memory. 

"Boy, I'll never forget it as long as I live," Hamill told Carson. "I sometimes dream about this line." 

We are not going to write the line here; you have to watch Hamill deliver it in character to get the full effect. But trust us, it's bad.
