MJ in
Spider-Man 3: Meet the Heroes and Villains
:D
(also, kudos for them acknowledging that acting is hard and MJ is a hard worker and she’s not frittering her life away on some vapid profession, as some folks would have it.)
IDK how you feel about tie-in novels, Sarah, but I think you’d really like Diane Duane’s Spider-Man novels – each of them has a major secondary plot running about MJ finding work (my favorite was the one featuring her brief stint as a voice actress for a superhero cartoon). Her acting career is pretty important in Adam-Troy Castro’s Gathering of the Sinister Six, too.
(GSS is regrettably hard to find cheap these days, but Duane’s trilogy is basically a pittance + shipping on both Amazon UK and US. FOR THE RECORD.)
OMG yes I love tie-in novels. That sounds awesome! (And you’re right, they’re super cheap. :D)
