Ouijas gives us the heebie-jeebies. The idea of summoning the dead is always creepy, but people still keep whipping out the Ouija board -- or use other means -- to call forth evil spirits. As 'Ouija' hits theaters, let's look back at some of the movies' most memorable ghost whisperers. 

Oda Mae Brown in 'Ghost' (1990)

Whoopi Goldberg won an Oscar for playing one of the movies’ most famous mediums, Oda Mae Brown. In this hit film, she helps the ghost of Sam Wheat (Patrick Swayze) finish some unfinished business – in between steamy arts and crafts sessions scored to “Unchained Melody.”

John Constantine in 'Constantine' (2005)

Before he was starring in his own NBC series, Keanu Reeves played the popular DC/Vertigo demon expert in this 2005 thriller. In addition to talking to and seeing demons, Constantine can also travel to Hell to pay the undead a personal visit. 

Tangina Barrons in 'Poltergeist' (1982)

With her childlike voice and diminutive stature, actress Zelda Rubinstein creeped us out about as much as the spirits she conjured in this genre classic. 

Cole Sear in 'The Sixth Sense' (1999)

This poor, tortured boy took one look at Bruce Willis and said, “I see dead people.” Despite that, audience never saw one of the biggest twist endings ever coming. 

The Warrens in 'The Conjuring' (2013)

This movie is based on real-life paranormal investigators Ed and Lorraine Warren, who are so devoted to their profession that they have a room full of nightmare fuel -- with creepy doll Annabelle as the centerpiece. Now that the Warrens have both passed away, you gotta wonder if anyone has tried to summon them…

Lydia Deetz in 'Beetlejuice' (1988)

As her family’s “strange and unusual” misfit, Lydia (Winona Ryder) can see the dead -- specifically the previous owners of the house that the Deetz’ now own. The downside is dealing with Beetlejuice. The upside? A ghost-powered performance of a Harry Belafonte tune. 

Shaun San Dena in 'Drag Me To Hell' (2009) 

Actress Adriana Barraza reached out and contacted an evil demon in Sam Raimi’s underrated horror pic, becoming possessed by the spirit in the process. The only thing worse is the fate suffered by the film’s lead character. 

George Lonegan in 'Hereafter' (2010)

Like most ghost whisperers in the movies, George (Matt Damon) considers his ability to communicate with the dead a curse, not a gift. Despite the burden of a sixth sense, George is able to find somewhat of a happy ending. 

Frank Bannister in 'The Frighteners' (1996) 

Michael J. Fox plays a huckster-turned-ghostbuster who can really communicate with the deceased -- including a demonic spirit who’s out to kill people just for kicks.

Elise Rainier in 'Insidious' (2010) 

What do you do when your child falls into a mysterious coma, and his body is suddenly possessed by demonic forces? Freak out. Then, call in paranormal investigator Elise Rainier.
