If I ever get around to drawing up a list of my top 25 favorite non-blockbuster movies, Secrets and Lies would roll in very near the top. I have watched it a few times and expect I will continue to do so periodically.
The acting is phenomenal. It is an ensemble cast, for sure, no superstars, but three of the main actors: Timothy Spall, Brenda Blethyn and Claire Rushbrook, are among the best that Great Britain has produced. What I first saw this film, it was literally the first time I had seen those three perform, and I quickly learned to seek them out in other projects. I believe the movie won the top award at the Cannes festival, and Brenda Blethyn won a deserved Academy Oscar award.
The story is a powerful one, and allows for emotional growth in a few of the characters. A few Mike Leigh movies share more than just his favorite repeat performers: they also include a big emotional reveal at the end that really pack a wallop. This movie, Mr. Harvey Lights a Candle, and All or Nothing share that element. I have read that Leigh makes his cast aware of the story but allows them leeway in improvised dialogue, sometimes when he surprises them during filming, but I haven’t studied his technique in any detail.
I could go on and on about this favorite movie of mine, but I wouldn’t want to risk diminishing the impact for anyone who hasn’t seen the movie yet. Just watch and enjoy.
