Limiting a left join to returning one result?

Question

I currently have this left join as part of a query:

LEFT JOIN movies t3 ON t1.movie_id = t3.movie_id AND t3.popularity = 0

The trouble is that

Answer 1

LEFT JOIN movies as m ON m.id = (
    SELECT id FROM movies mm WHERE mm.movie_id = t1.movie_id
    ORDER BY mm.id DESC
    LIMIT 1    
)
