While shooting is underway, a 143-pound Matthew McConaughey is surrounding himself with some great supporting actors for his HIV/AIDs drama The Dallas Buyer’s Club. We’ve already got Jared Leto and Jennifer Garner in the project directed by Jean-Marc Vallee (The Young Victoria) and now Variety has two additions.

Joining the project is The Grey and Walking Dead star Dallas Roberts, who wil play defense attorney to McConaughey’s Ron Woodruff character. Steve Zahn, who last worked with McConaughey on Sahara has also joined the project as a police officer who copes with Woodruff, due to his father’s personal struggle with Alzheimer’s.

In other McConaughey news, the actor is currently doing the dog and pony show for his awards-friendly roles in Bernie, as well as Magic Mike, and we’ve got an update on a sequel to the latter movie. We’ve heard Channing Tatum discuss the prospects of a sequel, but things have been quiet on his co-star’s end, until now.

Speaking with HitFix, a frail McConaughey said he loved playing the character, especially Steven Soderbergh‘s insistence on improvisation. He even added that he’s talked with the filmmakers about coming back for Magic Mike 2, saying, “I’ve heard a couple of the storylines they were floating around. I won’t share them ’cause neither one of them may end up being what it is, but I’ve heard a couple of storylines, and if something comes back that I get to look at and I can go, ‘Boy, I know how to be Dallas in that tonally, too, you know,’ then it’d be a blast to do it – to step back in Dallas’ shoes.” Check out video from his interview below.
