The Guests at the Funeral (Situational Irony)
Throughout the whole film, Will maintains that most of the elements of his father's stories are completely fictional. While his father gives detailed accounts of his many exploits, they seem too far-fetched to have any basis in reality. Thus, it is ironic when Will shows up to his father's funeral and sees all the characters from his stories in attendance. While they are somewhat less fantastical than described in his father's tales, they all match his descriptions in key ways.
Norther becomes a bank robber (Situational Irony)
When we first meet Norther Winslow, he is an acclaimed (if uninspired) poet. In Spectre, he is considered an artistic genius and lives a refined and artistic life. Therefore, it is ironic when, later on in western Texas, Edward runs into him robbing a bank. After Edward tells Norther about the failing Texan Savings and Loans economy, Norther runs off to Wall Street to make big bucks. The refined poet becoming a bank robber and then a Wall Street trader is itself an ironic professional shift.
Spectre is Deadening (Situational Irony)
Spectre is considered to be the most perfect place on earth, an idyll in the middle of the forest. Guests even give up their shoes upon arriving to symbolize their intention to stay. Everything anyone could ever need in life can be found in Spectre. Ironically, however, Spectre's perfection has its drawbacks. The poet cannot write good poems, and conversation can be lacking. Thus, in an ironic twist that surprises everyone in the utopian town, Edward chooses to leave, as he knows there is more to life for him than simple stationary bliss.
Sandra thinks Edward is dead (Dramatic Irony)
When Edward goes to war, he undertakes a dangerous mission and is presumed dead by the army, who pass along word of his death to Sandra. What she doesn't know, however, is that Edward is on his way back to her, with no way of getting in touch. The discrepancy between what Sandra knows and what we know about Edward's survival creates an instance of dramatic irony.
