So, the infographic shows Selma being wholly true. But, when it came out, it was controversial for allegedly rewriting history to make LBJ a civil rights villain:
The makers of the new movie “Selma” apparently just couldn’t resist taking dramatic, trumped-up license with a true story that didn’t need any embellishment to work as a big-screen historical drama. As a result, the film falsely portrays President Lyndon B. Johnson as being at odds with Martin Luther King Jr. and even using the FBI to discredit him, as only reluctantly behind the Voting Rights Act of 1965 and as opposed to the Selma march itself.
In fact, Selma was LBJ’s idea, he considered the Voting Rights Act his greatest legislative achievement, he viewed King as an essential partner in getting it enacted — and he didn’t use the FBI to disparage him.
To be sure, that linked, quoted piece is biased and not without its critics; that "Selma was LBJ's idea" is particularly hotly disputed, and other claims are open to debate (see this Amy Davidson New Yorker piece, for example
) - but nonetheless, there is controversy about the accuracy of the film that the infographic doesn't reflect.
