January Jones, 33, may be basking in the success of the new X-Men: First Class movie, which nabbed the top spot at the box office after Friday's release, but she is dodging criticism about her performance.

Damon Lindelof, 38, the co-creator of ABC's retired show, Lost (which received its fair share of criticism a few seasons ago), took to Twitter to express his polarized opinions about the movie. Altogether, the producer said, he "Dug FIRST CLASS … especially [Michael] Fassbender, [James] McAvoy and the best deployment of the PG-13 single-use eff-bomb I have ever seen." Not all of his praise was glowing, however. When it came to Jones' role as mutant character Emma Frost, Lindelof tweeted, "Emma Frost's THREE mutant powers: Telepathy, Transformation to Solid Diamond and last but not least, Sucking at Acting."

Though Lindelof has been known to publicly spar with colleagues in the industry before, such as Game of Thrones' writer George R.R. Martin, 63, who said he did not want his show to follow the Lost path, Lindelof is not the only Hollywood insider who has less-than-kind things to say about Jones.

Zach Galifianakis, 41, remembered a tense encounter with Jones. "I sit at her table and talk for 10 minutes, and she goes, 'I think it's time for you to leave now,'" The Hangover star said about Jones in a May interview with Shortlist.com. "So I say, 'January, you are an actress in a show and everybody's going to forget about you in a few years, so f**king be nice,' and I got up and left."

The Mad Men actress, who announced that she was pregnant in April but still has not revealed the father despite rampant speculation that it may be SNL funnyman and Jones' ex, Jason Sudeikis, 35, has not yet responded to her vocal critics.
