- Arthur has a journal of jokes that he fans through twice. Each time, one small picture is visible (that appears to be fleshy with scribbles over the pix) that may or may not be nudity. It's not even worth mentioning as the images are completely indiscernible.
- There are mentions of sexual roleplay in relationships by a comedian. However, the scene cuts away before the joke gets graphic.
- In the scene where Arthur receives a call inviting him to be on Murray's show he is lying on his bed with his hand down his underwear implying masturbation. However, it is brief and in the background, also easily missed.
- Arthur comes to his neighbor's place and passionately kisses her.
- Signs containing risqué titles and suggestive images outside pornographic theaters. No nudity.
- One of the ending scenes has a pornographic picture on a billboard behind the title character and can be seen for the duration of the scene. The picture is distant. It's noticeable, but extremely hard to make out. The caption "Ace in the Hole" and a picture of a person (man? Woman?), is very hard to discern.
