Matthew McConaughey reveals wild physical brawls with longtime pal Woody Harrelson: 'Blood has been drawn'

Matthew McConaughey has lifted the lid on his real-life brawls with longtime pal Woody Harrelson.

Though the Hollywood icons have been close friends for nearly 30 years, McConaughey, 56, revealed that some of his physical fights with Harrelson, 65, have ended in blood.

'Blood has been drawn,' McConaughey told Entertainment Weekly while promoting his and Harrelson's new Apple TV series, Brothers, which premiered on Tuesday. 

'No broken bones. Blood has been drawn, though, and will be drawn again,' he added.

Harrelson said that the two 'butt heads' often and that there was a situation that ended in a 'chipped tooth.'

'Cracked lip,' Harrelson added, 'That kind of thing.'

McConaughey clarified that Harrelson was the one to chip his tooth.

He also jokingly added that Harrelson 'accidentally overswung' and hit him in the jaw.

'One of the great athletes of all of time with incredible special sense,' he said, pointing at Harrelson. 

'Such a bulls**t excuse when he says, "Oh, I didn't mean to extend it, miss it by four inches long." He knows exactly where every part of his body is.'

Harrelson said that the accidents between them go both ways, and that despite their bust-ups their friendship remains solid.

'In the end, we f*****g love each other. We hug it out. We mix a drink. Everything's groovy.'

The dynamic duo first met in 1997 while filming the comedy EDtv. 

Their most famous collaboration came in 2014, when they starred on the first season of HBO's True Detective as Rustin Cohle and Martin Hart. 

The two have recently reunited once again for the Apple TV series Brothers, a comedy that plays on the wild theory that the two Hollywood stars might actually be half-brothers.

The speculation initially kicked off after McConaughey revealed his mother, Kay McConaughey a.k.a Ma Mac, once claimed she 'knew' Harrelson's father - convicted contract killer Charles Voyde Harrelson - around the time that McConaughey was conceived. 

The two have now turned the rumor into an eight-episode series. 

McConaughey and Harrelson recently spoke with The Hollywood Reporter about their idea for the show, with the Oscar winner sharing, 'We'd been chatting for years, and it was becoming quite an entertaining narrative amongst he and I and our families every time we got together since my mom said that line that night in Greece [about Harrelson's dad].'

'He’s the engine trying to get it done because he’s the one who believes it’s true, and who wants it to be true! For us to be brothers,' McConaughey added.

'It is true!' Harrelson quipped, adding, 'because Ma Mac did say, "I knew… your father."'

McConaughey joked that for Harrelson Ma Mac's statement 'means more than a DNA test. And if a DNA test comes out and says we're not brothers, he's gonna say, "That’s why you can’t trust science."'

McConaughey was born in Uvalde, Texas, while Harrelson was born in Midland, Texas, divided by roughly 279 miles.

The best friends later pieced together that Harrelson's father, who was involved in dozens of murders in the 1960s and 1970s, had been on furlough around the time McConaughey's parents were getting their second divorce.

Harrelson then said that McConaughey refuses to take a DNA test. McConaughey explained that if it turned out Harrelson's father was also his father then he'd need to 'unpack 56 years of who I thought my dad was.' 

Harrelson also said that McConaughey 'is more my brother than my brothers in reality, for years and years.' 

Harrelson's father received a life sentence for the 1979 murder of a judge. During childhood, Harrelson had little contact with his father, who abandoned the family when he was seven. 

As an adult, he tried to rebuild a relationship with Charles, visiting him in prison until he died in 2007. 

The first two episodes of Brothers are now available on Apple TV. New episodes will premiere every Wednesday through November 4.
