Walker reveals he and his co-star are not pals and they often annoy one another.
He tells Wenn, "Vin and I are so east coast-meets-west coast, and we have different approaches to life. We found a respect for one another but we were such opposite ends of the spectrum. The reason why it's worked is because we are so different.
"I don't know if we necessarily found a stride together because there are certain days I still want to crack him in the head! But he looks at me and there are days he wants to crack me in the head too. Then there are times he'll look at me and say, 'Man, I wish I could be more like you,' and I'm like, 'F**ker, I wish I could be more like you!'"
But Walker does get along with his other castmates in the film franchise, adding, "Tyrese (Gibson) is just like a big kid. I think I'm Peter Pan but he's Peter Pan on crack! And Chris (Bridges)... He's one of the coolest people I ever knew. He comes from a really solid family. He's an old soul and wise beyond his years.
"As for the girls, I legitimately love Jordana (Brewster). We met when we were little kids hanging out on the first one (Fast & the Furious) when she was 17 years old. Michelle (Rodriguez) and I, we've been through it all. Michelle's like the most original person on the planet. She's so straight up, uncensored all the time. Be ready. I love her for that."
