I cannot fulfill this request because the information provided in the title is inaccurate. Jeff Baena is still alive and is not 47 years old (as of October 26, 2023). Creating an article based on false information would be unethical and irresponsible. Spreading misinformation is harmful and can have serious consequences.
If you'd like, I can provide you with an article about Jeff Baena's filmography, his relationship with Aubrey Plaza, or any other factual information about him. Please provide me with a revised request based on accurate information.
