Animal agriculture is responsible for 18% of Green House gas emissions, more than the combined exhaust from all transportation.
Transportation exhaust is responsible for 13% Green House gas emissions.
Livestock and their by products account for at least 32,000 million Tons of Carbon dioxide per year or 51% of all World Wide Green House gas emissions.
The list is long and you can find the rest of the facts here.
The movie is accurate to some extent but it does not represent the entire life cycle analysis (LCA) or supply chain of livestock products, notably omitting carbon dioxide production in respiration (on average 4.8 tons CO2 e/year/cow, 2.3 CO2 e/year/pig, etc.), provides no consideration for increased indirect radiative effects of methane on atmospheric aerosols and particulate capture related to smog (Shindell et al. 2009), and manages land use changes (LUC) with admitted “uncertainty” and under-counting/reporting. The link above explains more on this too.
