A full house welcomed Josh Radnor home to the Drexel Theatre Friday night for the premiere of "Happythankyoumoreplease."

Radnor, who grew up in Bexley, wrote, directed and played the leading role in this Sundance Film Festival Award-winning film.

He is best known for his role as Ted, the central character on the CBS comedy, "How I Met Your Mother."

After the movie opened for a limited engagement, Radnor was present to answer questions.

He explained that even though his movie has been shown in theaters across the country and also in Spain, seeing it on the screen at the Drexel Theater is "sentimental" for him.

"I have happy memories of seeing movies here," he said, recalling coming to the Drexel as a child with his father to see "Robin Hood."

Radnor said his success didn't feel real until he looked at the marquee Friday.

"I saw the 'welcome home Josh Radnor' and was like 'whoa'I just feel super grateful," he said.

Radnor said he was happy he was able to stand in the back for some of the showing to see the light of his movie reflect off of the audience's faces. He said he enjoyed seeing their reactions.

In the movie, which originally debuted in September 2010, Radnor plays Sam Wexler, who finds a young boy on a subway and agrees to let him stay with him for a few days.

Together, the cast learns the struggles of what it is to be young and how finding out who you are does not come from desperation, but rather determination of finding out who you want to be.

Using music from breaking indie artists was a key element in his story line.

"The movie itself wanted to be resolved with a song," he said.

The movie ends with his love interest Mississippi (Kate Mara) singing a song about happiness while different scenes show his circle of friends resolving their conflicts.

He hopes the concluding song provokes interesting conversation and gives the movie life beyond the song.

When Radnor started writing the script he knew he wanted it to end with the song, "Sing Happy." He admitted, "I didn't know who would be singing it or why, I just decided that more movies need to end with songs."

When the credits rolled the packed Drexel Theater cheered loudly when Radnor's name appeared on the screen. After the lights came on he walked down the aisle and received an even warmer welcome of cheers and applause.

He then answered the audience's questions for about 30 minutes before showing his movie.

"Happythankyoumoreplease" was his second screenplay, but the first one produced.

The film won the audience award for favorite U.S. drama chosen by Sundance fans at the 2010 Sundance Film Festival as well as the Audience Award for Best Dramatic Feature at the Maui Film Festival.

Jesse Hara, also a Bexley native, produced the film and is working with Radnor on a new feature film. Production is scheduled to start this summer at Kenyon College in Gambier, Ohio, where Radnor is an alumnus.
