Dennis Quaid's on-set rant was just a joke, guys! "I am acting here!"

It was all just a joke, you guys…

UPDATE: 

Dennis Quaid isn’t actually a jerk, you guys! He had us all fooled.

No it wasn’t a prank for the Jimmy Kimmel show, but it certainly wasn’t a real ‘on-set rant’ either.

The angry performance that was “secretly” filmed on an iPhone showing Dennis Quaid “freaking out” on-set, was just part of a new Funny or Die video.

Watch below to understand just why Quaid says, “This is horseshit! I’ve got these fucking zombies over here that I have to look at, I have a bunch of pussies staring at me, and this fucking baby. This is garbage.”

There needs to be Oscars buzz about this stunning performance.

Actor Dennis Quaid, most famous for cheating on Meg Ryan, has been filmed in an apparent on-set meltdown.

The video was taken on the set of his new film, Truth, and it. Is. Amazing.

So amazing, in fact, that there’s a question as to whether or not the video was made as a prank for late-night talk show host Jimmy Kimmel.

In the video, shot from a phone (in unprofessional vertical view) and apparently taken mid-scene, Quaid looks to be wearing his angry pants.

“What the fuck? Keep going. I am acting here, and this dickhead here wanders on my set!” he yells, throwing himself into the performance with much finger-pointing and gesticulating.

“I can’t even get a line out, until dopey the dick starts whispering in your ear and you’re not even watching anymore!”

Someone tries to placate the infuriated performer, but he will not be talked down.

“Don’t fucking ‘Dennis’ me! I am doing my job here. I am a pro. This is the most unprofessional set I have ever been on. This is horseshit! I’ve got these fucking zombies over here that I have to look at, I have a bunch of pussies staring at me, and this fucking baby. This is garbage.”

There are sounds of a Quaid storm off and his parting shot.

“Blow me.”

In favour of the video being real? Dennis Quaid cheated on Meg Ryan and therefore is clearly a douche bag. Secondly, at one stage the amateur camera-person points the phone down at the floor, presumably to avoid the wrath that would ensue if Quaid discovered he was being filmed.

If it’s real, it’s truly spectacular, though we can’t help but feel sorry for the “fucking baby.” It’s a tough industry, kid.

And if you’re now in the mood for more celebrity dummy-spits, this is the ultimate.
