T.J. Miller wants to return to the Deadpool universe in a potential fourth installment, but only if Ryan Reynolds asks.

Deadpool & Wolverine featured the return of Hugh Jackman as the beloved hero from the X-Men franchise. The Les Misérables star hadn't portrayed the character since Logan, the dramatic story that presented the hero's death.

While interviewing each other for PEOPLE's first-ever collectible side-by-side covers, Jackman opened up about his close friendship with Reynolds, telling him, "Ever since I've known you, and I would say in particular in the last five, 10 years, we've had more time where we go for our walks because you're an unbelievable listener ."
